So many people hawking wafflepool.com and
http://www.clevermining.com/ is so much better.
If you WERE going to leave middlecoin I'd go there.
Or both, for failover and redundancy. I have my cgminer.conf set to send 30% each to Middlecoin East and West, 20% to Wafflepool, and 20% to Clevermining.
Which should ensure that no miner ever sits around waiting for work, two pools can simultaneously drop off the net without affecting more than a day's profits, etc.
Hardware stable and auto-healing: check. Redundant pools: check. Ongoing work: verifying deposits every couple days. *feet up* *beer in hand*.
