KPS 88 - exceptionally stable due to the weight which helps on volleys (no twisting on anything off-centre) BUT, due to the weight, swingweight and only moderate balance it is exceptionally slow through the air which is a limitation on volleys.
TT Warrior MP - Ultimately, I found it to be far too light. It's nice to volley with and makes spin easy to generate but it is quite anaemic.
PSL - a genuinely nice all-around racquet with good touch but it isn't overly powerful, has a tight string pattern and is a bit light-weight SO you'll need to either add some weight (it does give you a lot of leeway to do that and not make the racquet too cumbersome) or be able to generate your own power and spin.
BLX 90 - Stable like the KPS88, but so much easier to swing. Power, spin and control are all good. Only trouble is that it lacks some mobility.
Personally, the PSL and BLX 90 were my favourites but, if I were you, I'd also try the Prestige Mid. It's very stable (not as much as the BLX but moreso than the PSL) but still quite mobile (not as much as the PSL but moreso than the BLX).
Also: don't limit yourself. I serve/volley and chip/charge most all of the time and I found the Pure Drive to be an excellent racquet for that style of game. Ultimately it lacked the feel I was looking for but for volleying, serving, chip/charging it was exceptionally effective.
