The Raven's have been a dream so far. They mount easily and stay on well (I use Effetto Mariposa tape). They roll well like my corsas and conti competition and have very good grip which gives me confidence in winter conditions or rain. I ride them on 27mm-wide Bontrager Aeolous rims which means that they sit very well on the rim. I am 165lbs and use 85psi in the front and 80 in the back. Based on my experience so far and the riding that I do, I recommend giving them a try.
