BT023 Vs PR3

[flesh]

I've had BT020, 021, 022 and 023. I've also had PR2's and PR3's. Now I've got Metzeler Z4's.

All of these were chosen for longevity and wet-weather grip. THAT's what they're good at! According to your post, you're not interested in either, so these are not the tyres for you. Look at Michelin Pilot Powers or Pirelli Diabli Rosso, etc, etc.

Agree with MadDog on this. I have used all of the above Bridgetone tyres and, although grip is great, I find the 023's the worst of the Bridgstone range so far. Also had a set of PR2's but for some reason did get on well with them. Took me ages to scrub them in aswell. 
I currently have Michelin Pilot Powers on my Gen 2 FZ1 and they grip very well in the dry but do not seem as good in the wet. Also a much steeper profile than the touring tyres mentioned so the bike tips into corners faster than I'm used too  :\
