Be careful with coin switching pools. Because they bounce from coin to coin so much they can go for a while without finding blocks. Especially if profitability difference of coins is small. I've noticed that some are not accurate either. They switch to most profitable but by the time you get confirmations to deposit to your wallet and then send to an exchange traders on the exchange will dump anticipating the miners.
I used to deal with in mining FTC. By the time I got coins to btc-e the price collapsed. So I left the coins there waiting for the next pump.
Both the mining and the selling are linked together. If you are basing your decision to mine purely on the most profitability, you're actually mining behind the curve.
A coin switching pool like middlecoin pays out in btc. they take care of auto-switching to a coin, but take into account how the trade bot will sell the coins. all of that precise timing is taken care for me, and i can let the farm mine for weeks without touching anything.
I just want to mine and not micromanage my trades. i would recommend a coin switching pool that pays out in bitcoin or litecoin. the wallet gets paid out and i never have to login to an exchange and worry about price fluctuation. this is a fair tradeoff for me because buys free time for me to do non-mining/trading things.
