Ohlins is supposed to be the best, but I've never tried them. The KYB shocks found on Kawasaki ZRXs are very good (I have some), with one caveat: They are made for a heavier bike.
They're Thruxton-length, have preload, rebound and compression damping and can be adjusted to suit. They are also rebuildable and could be resprung with lighter springs if desired. I too run fairly aggressively in the twisties and the KYBs are perfect for me. Preload is at the lowest setting, rebound is on two and compression is on three. As I weigh in at around 250lbs in full gear, the ride is just right.
KYBs show up on ebay fairly regularly at around $400. Even having them resprung, they may be cheaper than the cost of a new set of Ohlins units.
