I began following Edison wedges about 2 years ago and finally bought a 54 degree wedge (53 degrees bent to 54 degrees, steel shaft) because I was convinced that it might help my short game. A few months later the PING rep showed me that I got a lot more spin with the PING Slide 4.0 wedges. Since our greens are very small (Stanley Thompson Course) I decided that lots of spin was important and bought PING Glide 4.0 wedges (graphite 50, 54 and 58 degrees) instead of buying additional Edison wedges. (My pitching wedge is graphite, PING G400, 46 degrees.) I continually wonder if the Edison wedges would have worked any better. Our courses are mostly closed here in Canada, but we have an awesome set of simulators nearby. I spent 1 day every week there last winter and plan to do the same this winter. After each session I receive a Summary of all the shots that I have taken (distance, height, spin, ball speed, dispersion, etc). It is very easy to compare summaries of different clubs. I really would like to do this because I am still wondering whether my next set of wedges should be Edison. The simulator set up and feedback Summaries will make it very easy to compare the Edison and PING wedges. I am 71 years old and my handicap is 20.0 Thanks for this opportunity to enter as a possible tester.
