The Tour Series E/S Wedges with Micro Groove Scoring Lines were designed after extensive testing of the top 4 wedges used on the PGA Tour, as reported by the Darrell Survey. The shape of the heads of the Carbite Tour Series E/S wedges, including the leading edges and soles are similar to other wedges costing many times more. In testing, Carbite held its own and the more expensive wedges did not test any better. Only the Carbite PBX tested better. Micro groove scoring lines produce exceptional spin, and provide great ball control from all types of fairway lies, and out of bunkers. PGA TOUR PLAYERS ARE STILL USING CARBITE WEDGES. ONE PGA TOUR PLAYER WHO WON THE U S  BANK TITLE, WITH A RECORD 26 ON ONE NINE, HAS BEEN USING CARBITE WEDGES FOR 18 YEARS.
