I don’t understand how bulge and roll really has anything to do with swing speed to see a difference. He’s basically got iron soles with hybrid faces, everyone agrees hybrids/fairway woods are more forgiving/go further, but minute Bryson does something it’s “only for his swing speed”. I think he’s a goofy sumbich, but I don’t think he’s crazy on the equipment development. There’s a lot of slow swingers with great reviews of hybrid iron sets, but clearly his idea can’t work.. ooook.
