Well.... I've been carrying it off and on for about 3 years now and I'm still not sure haha. It's a fun little change, and it has it's ups and downs. The pros are I can spydieflick it from either hand. But really, spydieflicking is the quickest, most reliable opening method. I think if I were to recommend it to someone, I'd tell them to do it to a large CRK because there's just more room on it. On a small Sebenza the hole has to be pretty small, on a large you can get away with a larger hole and then it might work more like opening a Spyderco. I can slowly open it with my thumb now days very well (in a fluid spyderco-like way), but it took a while to get used to it.
