I thought I had the curves set up rather well, indeed the front would have sent me over the bars but after one 2 hr ride found the rear to go a bit mushy and the front to have lost some of it's power, will fettle before condeming them but they do look a bit flimsy and an old mate of mine had a kona back in the day and he binned the curve stuff almost immediatly albeit for v's and lets face it, we all did that did we not?
