Up until I sold the bike earlier this year I was using Mitchelin Pilot Power 2CT's, being dual compound I found that they lasted a reasonable amount of time but performed well enough to run in fast groups on trackdays with no problem.
I think they might have been superceded but there should be more recent equivalent.
The BT-021 is pretty good from what other have said although I've never used it myself.
To be honest, if you're not going to be doing trakdays then I'd go for something harder wearing, you'd be amazed how hard you have to push even a more touring based tyre before it'll let go and if you're riding that hard on the road it's not going to make much of any difference which tyre you chose
