I've been playing 3 Edison 2.0 wedges (47, 51, 55 degrees loft) for a few weeks now. The feedback on every shot is exceptionally good, as is the spin and trajectory. This is my first time using graphite shafts, but after a day of getting used to them, I wouldn't want to be without them. I'm still using an old Eidolon 60 degree lob wedge, but next year at the latest, I'll swap it for an Edison 2.0 wedge. To summarize: These are my 3rd generation wedges from Terry Koehler and they are clearly the best for my game (my handicap fluctuates between 10 and 11)
