Proto-Concept developed three sole grinds that differ in effective bounce based on swing style.
The NT grind is on the lower lofts and is primarily for full swings. The SP grind is on lofts 56 and up and is designed for players with sweeping swings. The AG grind is another option for 56 degrees and up and is made for those who hit down steeply on the ball.
Groove width and depth have been optimised for maximum spin.
13 options (46-60 degrees), 3 sole grinds, 1 finish
“Hot List testers noted exceptional bunker glide; high, soft-launching shots; excellent greenside touch; versatile grinds and dependable spin that greatly rewards full-swing strikes.”
