The hyper hammer is too powerful and I want a heavier racquet with more spin.
I don't know how much your Wilson weighs, but if you want less power in a heavier frame, you should consider trying some options with a good deal of flex. Wilson doesn't have too much to offer these days among the softer crop of racquets available out there, but the Pro Staff 95 could be one to try given its flex rating of 62.
I've been loving my Volkl O10 325g's for about two years now and they're better for me than anything in the Wilson lineup - I haven't tried the PS or RF 97 yet, but I'm not in the market for fresh gear. My O10's are tuned with some lead tape for both the stability and balance I like in my frames. You may consider a little tuning of your own if you come across something that's close to what you're looking for.
So the Volkl 10 325g has been replaced with the current Super G 10 line. If those are too heavy for you, definitely get a look at the O10 295g, which is on sale at TW right now. This is an easy platform to tune into a setup you might like. Other frames with a combo of some heft and some flex include the Head Prestiges, Pacific X Force Pro, Prince Classic Graphite 100 and Tour 100... The TW demo program gives you the keys to the candy store.
I forgot to mention that my Volkls give me fantastic spin potential and I string them with 16 or 17 ga. synthetic gut - nothing exotic. Great hitters!!
