Wishon Golf 515 Graduated Roll Technology

Features:
515GRT stands for Graduated Roll Technology, an amazing and innovative face radius design from TWGT.
The 515GRT Beta Titanium Drivers' GRT 0 Roll radius design deliver a much more consistent trajectory for shots that are hit vertically off-center. All other drivers are designed with a 12" to 14" vertical radius up and down on the surface of the face, called Vertical Roll. As driver size has increased, face height has become much taller. On drivers of >350cc size, the conventional Roll combined with the taller face means the loft at the bottom of the face is as much as 3-4 degrees LESS than the real loft of the driver. And the loft at the top of the face is 3-4 degrees MORE than the real loft of the driver.
For golfers who occasionally-to-frequently hit the ball above or below the center of the face, this wide range in loft can mean shots hit low on the face fly much lower and lose carry distance. And shots hit high on the face fly much higher and also result in a loss of distance. The 515GRT variable Roll face design delivers the SAME launch angle for shots hit low on the face as in the center of the face. And the 515GRT face design means a better launch angle for shots hit above the face center.
515GRT 9.5 loft driver is designed for golfers who already hit the ball high enough from their typical swing movements, as well as for golfers who wish to hit the ball with a driving, penetrating trajectory. The 360cc size of the 9.5 driver is designed for adequate horizontal off-center shot forgiveness for this slightly-better-than-average to skilled player who typically does not require a higher loft or larger head size.
515GRT 11 degree driver is for most average golfers who hit the ball on a medium-to-lower trajectory and need a higher launch angle to maximize carry distance. The 395cc size is designed to offer greater horizontal off-center shot forgiveness for the average ability player.
The 10.5° 440cc - even more face area to take advantage of the GRT.
515GRT faces are forged in a 'wrap-around' face construction to keep all welding (plasma welding on the drivers) off the back of the face and maximize face deflection for the highest COR/spring face rating allowed under the USGA Rules of Golf. For precision, the faces are CNC machined both on the back as well as the front. TWGT computer modeled variable thickness has been proven to maximize ball speed from off-center hits for greater distance. 515 Driver face material is 10-2-3 Beta Titanium, an ideal alloy for strength + elastic modulus.
The 515GRT drivers are finished in a striking midnight navy blue see-thru finish, with satin polish on the exposed titanium surfaces.
515GRT Fairway woods are the first 3, 5 and 7-wood heads to achieve the USGA limit for COR of 0.830.
515GRT Fairway woods are designed with true 0" roll for a much more consistent launch angle and ball flight.
515GRT Fairway Woods are designed with a true forged "Cup-Face" construction to maximize the performance of the faces.
Head shape on the Fairway Woods is a classic slight "pear-shape", finished in midnight blue die coat with bright satin polished sole and face nicely matching the 515 Driver.
515GRT Fairway Wood body is investment cast from 15-5 stainless, face is cup-face forged from the new Carpenter Tour Alloy 275 with yield strength higher than Carpenter 455 and 465 alloys.

Wishon Series 9 Titanium Driver

Features:
Two Models Available - 400cc in 10.5° loft; 460cc in 10.5° and 9° lofts

The underside of the crown and skirt areas are CNC Machined thinner in specific low stress areas to remove weight from high on the head, which is then re-distributed internally to create the Center of Gravity and MOI specifications of each head.
Deep rear CG position in both heads for higher launch angle and more control.
Forged, Cup-Face, Beta-Titanium, CNC Machined Variable Thickness Face Delivers only a 2% drop in ball velocity for 1 inch off-center hits.
Pure 6/4 titanium body construction
TWGT unique GRT face design ensures consistent launch angle regardless of impact point and contributes to the incredible off-center hit performance of the 949MC drivers.
Hosel weight bore for custom swingweight/MOI assembly
Finished in a deep gloss ebony with silver metallic and bright satin polish highlights.

Wishon Golf Series 9 Computer Face Engineered Drivers and Fairway woods

Features:
Driver faces are variable thickness design for more spring off the face and better distance on off-center hits.
Driver faces are forged 10-2-3 beta titanium for a higher strength-to-elasticity ratio and more spring face performance.
The 10-2-3 Beta Titanium is Cold Rolled - this means better grain stucture of the metal for more consistency all across the face.
The top of the driver heads designed with less radius 10mm back from the top edge to prevent top crown flexing for more energy transfer.
COR rating of the driver faces is just under 0.830; #3 wood has a higher COR than other #3 wood heads because of the 6/4 titanium face.
915-360-14°, 915-420-15° and 915-460-13° Drivers are engraved HIGH LAUNCH DRIVER so golfers won't be intimidated by seeing a higher loft angle number than they are used to...
The High Launch Drivers are truly for the golfers with slow swing speeds who need a higher launch angle to increase carry distance.
#3+ wood face is 6-4 Titanium because the smaller face size of the #3+ would not exhibit more spring face with 10-2-3 Beta Ti.
#5+ and #7+ wood faces are Carpenter 455 forged high strength steel.
#5+ and #7+ face thickness is less at 2.2mm because the C455 steel has a higher strength than the the titanium, but because the C455 has a lower elasticity, the thinner face is required to maximize spring face performance.
Sole radius of the #3+, #5+, #7+ is less than the drivers because these heads are played off the turf where less sole radius means a more consistent chance of hitting the ball on the center of the face.
The side skirt areas on the outer toe, heel and back are thickened sections to increase perimeter weighting of all 915CFE heads.
Hosel OD of the drivers and #3+ wood are 13.0mm to blend better into the larger head shapes; Hosel OD of the #5+ and #7+ are 12.2mm to better blend into the head size shape of these fairway woods.
Driver faces are CNC Machined variable thickness to increase spring face performance on off-center hits; CNC Machining of the back of the faces ensures face thickness accuracy to within 0.08mm to deliver more consistency in the COR rating.
Fairway wood lie angles are slighly flatter than the drivers for a more consistent sole to turf contact and increased accuracy.
The larger the driver size, the slightly more upright the lie angle for more game improvement accuracy; I.E. larger heads are typically played by golfers with higher handicaps.
Headweight change between fairway woods is 10g to allow for 1" incremental length change to ensure proper distance difference. Headweights that are only 5 grams apart require 1/2" length change which makes the fairway wood distances too close to each other.
460cc Driver has 56mm face height; 420cc Driver has 54mm face height; 360 Driver has 53mm face height; #3+ has 36.5mm face height.
Finished in dark forest metallic gloss with satin polish sole and glass bead blasted highlights.
