I have been using a Head Youtek Speed MP 16x19 and have a Dunlop Aerogel 200 18x20 on the way. I like the PHT mains at 58 lbs, and PSGD crosses at 60 lbs on my current stick. Does anyone have any suggestions for the new 18x20 Aerogel 200? I know it will be less powerful and produce less spin than the 16x19 racquet. Thanks!
