Any new racquet will take some adjustment time to get dialed in. And you can always mod the frame to your liking. Don't know about the Head, but the PS BLX 6.1 95 and Donnay P1 16x19 both require some modding, IMHO.
I like the Donnay best with the 10 gram buttcap and 3 grams @ 12. Also, it needs a decent poly to get to most out of the frame. It's a monster on serve, very solid on volleys and very spinny and powerful on groundstrokes. A really nice frame, in my experience. Perhaps you should give it some more time.
