OSnap is a very cool hybrid of a soft elastic shaped main (otoro pink) and a stiffer round cross (Tour flex). Sort of the poly version of gut mains and poly crosses. The feel is unique because you have the crazy spin and controlled pop from Otoro but that is reined in further by the crosses. It’s like it gives up to a certain point and then you hit a wall. Not in an uncomfortable way but in a way that gives you confidence to swing out. I’ve been playing great tennis with this setup. I’m going to try a couple other hybrids but this is top notch and the current front runner for me
