I'm using 18 gauge kevlar mains with 17l gauge cyberflash crosses strung at around 42/48.
In an 18x20 I still get a ton of control. Kevlar feels soft and nice at low tensions, but it could probably still bug your arm as the feel is pretty crisp.
For me it felt like the string played amazingly the first hour, and then very well for the next few matches before it broke. After the initial tension loss it felt like it settled in and didn't stretch much more. At that tension it wasn't that low powered at all, had great feel, and it lasts longer than anything else I've tried. Control didn't suffer at all.
Oh yeah, and it has more spin than full poly.
