Actually after taking my demos back I gave donnay another chance and checked out the new dual core platinum 94 and was able to hit with it today. The OP wasn't kidding, it was the best serving racquet I've ever hit with. At least for flat serves, the thing bombs more than a pure drive. As for the ground strokes, I definitely need some more getting used to to comment. The dual core's (at least the platinum) feel alot different than the older ones, much stiffer/crisper but I much prefer them. Funny how with the older ones I couldn't even fathom owning, and now the platinum perhaps is ending up on my list of considerations.
