i ride a 67" -11 strada with double stradaboots and i love it, at the start of the season it did not work for me, hardly even got through 32, got some coaching and runned it, again and again and again, 34 mph no problem runned 36 for the first time yesterday but before that i've got a couple of 5s and 4s but as the speed goes up the strada feels better and better for every pass, incredible ski!
