I'll be launching a public profit switching pool from my private code in 2-3 months. Mine there -- 100% custom work, not using any of the yiimp/yaamp frontend. It'll be more profitable (based on my myr-gr mining experience) than nicehash. My profit switching algo is better than anything I've seen elsewhere and unlike zpool.ca -- I won't be stealing 20% of your coins. Payouts will be in ETH (first profit switching pool to payout in ETH instead of BTC -- too many transaction issues with BTC and very high fees).
