I have played in both Ice bowls so far with Discraft only. So far the transition hasn't been difficult. The biggest transition was midranges because how intimately I knew my rocs, but now that I have a few rounds in I am loving the ESP Wasp. Very stable and predictable and as a bonus it and my ESP Buzz are faster than my rocs were. The one thing lacking with my rocs was the extra 30-40 feet that I could never get, but the Buzz especially is much faster and glides great and is predictably stable. I won the Mt. Airy Ice bowl by 6 over Matt Blakely and yesterday I won the Banklick Ice bowl by 1 over Blakely. I am still looking for that "fast and stable" disc. The Surge is fast and goes a long way, but can be touchy when it is windy like yesterday. I found myself throwing the ESP Avenger most of the day, but I do lose some distance when I go that route. In closing I am excited about the fact that my game hasn't suffered throught the transition, infact I don't feel as burdened by the choices that I used to go through before. The Avenger pretty much does everything, now if I could just throw it further! Oh, and as a bonus the Drone is the bomb. You see I grip my drivers differently than my midranges and putter (Dave Feldberg), but the rim on the Drone is so wide that I can use my driver grip. I birdied a very tough hole 12 both rounds yesterday( about 365 slightly down hill with fairway sloping from right to left) with the Drone!
