Why are you switching? I also like the Six.One Team. For the past few months I've beenusing the Pro Staff 95S, which is a LOVELY racquet but quite low-powered. More recently I've been hitting with the Six.One 95S (which has good power), but I'm still not sure I enjoy hitting with it. I can't put my finger on the problem -- maybe it's the balance, but I put a leather grip on and it still feels off. That said, people I hit with say THEY notice more power and spin, so that's something.
Have you tried the blade? I have an old kfactor kblade 98 that I hit with recently -- too much power, but cracking good on the serve. I haven't tried the new version but if you're looking for controllable power, that might work for you.
Another racquet in my bag is a Slazenger V98 Team -- good power, good spin potential, nice and light if that's what you want, or you can modify it with lead easily. If you can find one on the bay (it's discontinued), that might be worth a try.
