The BT023s seem to get good reports, although I have not used them myself.
I can't fault the Pilot Road 2s in all the conditions I have tried them in, and it has been pretty well the best and worst (rain, hail, hot, cold, gravel). I have used 2 sets of them in the last year, 32,000kms or so.
And yes I have been through Kangaroo Valley on them!
