x11 is crap, have you not seen 1TH getting switched around on these coins by individuals. GPU miners have no chance.
Make it qrk or scryptN, even x13 would be better.
I'm starting to think that even x13 is same made by same people that have some mashines that beat gpu's by far, which is why we see so many coins(same group launching bunch) mining most selling off repeat. but summertime keep miner's away from scrypt-n , go vert !!! and Lion
