Ross, the EXO 100s are fun, very fun, but you probably wouldn't like the soft feel of them. Basing that on your love of the APD, TFight, Prestige -- all of which are crisper in feel. The stiffness from those frames also make them much better at the hard flat serves, which is something I could never master with the EXO 100.
But your loss against a 5.0 guy sounds like much more of a player thing than a racquet thing. I think you're better off just sticking with the APD or the Prestige rather than venturing into Prince territory.
