Hey,I am planning to order some demos next week of these three frames: Dunlop biomimetic 500 tour Dunlop bio 300 (non tour) Yonex rdis 200 lite. My main questions are what I should expect from each of these coming from a stock mg radical mp. I'm looking at the 300 and rdis as a possible alternative to the radical that I hope will help give me more power and spin on groundies and serves. I don't want to deviate too much from the radicals specs as my game has become somewhat grooved to them... Anyone have anything tomsay about either of these?
