I ran through 2 sets of Bridgestone BT016 Pro's averaging about 4,000 miles (on each set, with more than 1/2 of that mileage in the mountains). Overall they were decent tires but I just never felt "connected" to them. They were pushed to the edges and never did anything wrong, steering was neutral and traction was always there, so other than feeling somewhat stiff of sharp edge bumps there isn't much to complain about. I decided to try the Q3's and I must say I am impressed so far. My wife and I completed 675 miles in two days, with all but 120 miles being mountain riding and so far I really like them. The steering quality, bump absorption and traction are all excellent and there is very little tire squirm. They remind me a lot of the Dunlop GP211's in just about every way which is a really good thing in my book. Last week I was able to go for a ride through the mountains solo and came away even more impressed. I typically ride very conservatively on the street, but did wick it up through a small section of the road to scrub the tires in to the edges (can't have any chicken strips) but found you damn near have to be dragging your knee's to use all of the tires up. It's extremely good to know there is that much cushion available if it was ever needed. Overall, I now have just at 900 miles on these tires, I really like them and would not hesitate to recommend them based on performance. Not sure what the mileage will end up being so i cannot comment on that.
As a footnote, these tires have made me fall in love with the Busa all over again and were an excellent match to my revalved and correctly sprung suspension.
