Ooh glad of the recommendation! I'm picking up the XTZ next Saturday and I know it needs new tyres already...
I'd been thinking of trying Shinko 705 but open to other suggestions on 80/20 adv tyres!
I fitted a set of old Trailwings to my XR a couple of years back and could barely unstick them on the road, even at big lean. The front was very impressive, good feel, considering. They were fine for some off road trails too, though were shit in sand and mud like any other 80/20 tire.
Pirelli Scorpion STR put on the other day, can't believe how much better the bike handles.
