Looks like Wilson have discontinued / are discontinuing quite a few replacement grips eg. True Grip
, Pro Hybrid, Performance Hybrid, MicroDry, [K]ontrol, K Grip etc. Disappointing that they're getting rid of True Grip (nice, heavy, chunky but not too chunky grip) and Pro Hybrid (nice mix of leather and synthetic, firm but not as firm as leather, thin but not too thin). Made for good grip options depending on racquet / personal preferences.
Get 'em whilst retailers still have stock if you want 'em!
