To answer your question - YES...IMO, just more bull puckey from the Marketing Department of the shaft manufacturer. Most amateur golfers, 95%, don't have the swing speed, timing nor physical ability to even play stiff flex shafts in their clubs, let alone a wedge flex shaft in their wedges. Putting a piece of rebar in their wedges might soothe their ego but does nothing to help their game in the least...What we as amateurs need is more short game practice instead of long drive practice and stop trying to "buy" a game with the latest and greatest "technical improvement" and gimmick from the marketing department of True Temper, et el and the glowing articles about them in the suck-up Golf Magazines written by company shills...
