I had some old Avon Azaro's (not 100% on the exact model) on my B4 and i personally thought they were great. In the dry there was plenty of grip, feedback was pretty nice. They did take a while to warm up in the wet (but then most tires do so..)
Wet weather in general was average not wonderful by any means and give it too much brake you were next to guaranteed to slide a little but all in all i thought they were a great set.
Personally on my 600 the only one's i can truly say anything about are Bridgestones BT020's they made my bike feel much more responsive, they stick well on the road, seem to be lasting well and on top of all that there good in the wet and cold (plenty of that in the UK). Only downside to these are there expensive but as the old saying goes "You get what you pay for!"
