I really liked mine until it sagged too much and couldn't be tightened anymore. I even laced it, which worked for a while, but still got a bit saggy.

I've seen a couple of other SAs in person, and others seem to just let it sag & find it comfortable. I tried to keep mine pretty tight because when it got hammock-y, the cutout would chafe me and it would make me feel like my saddle was too low. If I'd been able to let it be a little looser, it probably would have worked.
