Something quite dead or hibernating could benefit from that.
If tenebrix/fairbrix is even scrypt you could try those.
The recent newly released coins are very difficult with that kind of hashrate, so many people jump in to them in the beginning.

Maybe one of the (junk) coins with lottery like super blocks?
