In 2008, when I got custom Scratch wedges (Ari Techner of GCA) and a custom Edel Putter (from David) I went from a 6.0 to a 4.5 index, won the stroke play club championship for my flight, runner up in the match play club championship in my flight, and finished second in the player of the year standings at my club.
This custom stuff works, if you're serious about your game.
