Hi Tim,
I have two bikes. They both have these saddles on them. I started riding last May after a long layoff and tried Selle? SQ Lab, Oval and a few other and I really love thiese Infinitys. The saddle kind of cradles you. No sit bones discomfort at all. If any "breaking in" it would be your leg creases as one pair of cycling shorts became not wearable as it irritated that area a little as compared to my other shorts. Have a few metric centuries under my belt and so far so good. I just got an email from them inviting me to the start of the Race Across America in CA to take sneak peek at some new products just launched (not on website yet). I got interested in them after the testimony of some long distance riders. They do offer a 30 day trail, I believe. Let me know how you make out, if you try one.
