ive only had 2 sets of tyres on the 10R first were pirelli corsa III's and dunlop sportsmarts the differance is unbelieveable though the corsa's were very uninspiring confidence wise and i could never really tell what was going on with them, very poor feedback when tipped into a bend and dont even get me started on them in the wet, when it was dry and they were warm they did have a shed load of grip but i didnt feel i could really push them too hard as with the lack of feedback there didnt seam to be a warning that you were approaching the limit u just got right up to the limit with loads of grip and then they would give up, having spoken to my brother who used to do short circuit racing he mentioned he never rode pirelli slicks as they were the same more outright grip then a lot of tyres but if you tried to push just a lil bit more then there limit ud be in the gravel
the sportsmarts are great loads of feedback and they feel happier when lent over then they do upright ridden with em all over the place including a germany trip and 2 laps of the ring and they still have loads of grip left and after a perticulalry rain soaked session out in germany and still making some rather rapid progress with maybe 1 or 2 lil rider error hic-ups, but they still gave me enough grip to scrub off speed (panic brake) and make it around the corner (tip it in and pray), id have no issues taking them out on even the wettest day
