I've switched to
http://www.coinmine.pw for the time being until things pick back up for clevermining and the other pools. I like that coinmine.pw actualy supports vardiff too

Something clevermining use to support once a upon a time.
Do they have the auto-payout in BTC feature? Or is it just another multipool?

No autosell, you have to trade the coins manually/yourself.
It's easy to claim high profitability if you don't exchange to BTC and don't deliver BTC. Guess what. There's a coin which can give 180% LTC theoretical profitability. The only problem is that it's only on some very niche exchanges and its trading volume is 1 BTC/day and orders depth is for 0.1 BTC. The 180% LTC is purely theoretical. You can have it for 0.1 BTC worth of coins and then you need to go back to less profitable coins for the other 99.9 BTC.
CleverMining is about real profits, not theoretical speculation. I'm not going to leave you with bunch of niche coins which you won't know what to do with. Mining coins is only part of the equation. You need to actually sell them to get your profits. It's worthless to make profitability stats based on coins which you won't be able to sell.
The altcoins market is really bad these days but I'm working very hard to deliver the best profitability among coin-switching pools. What I've been working on for the whole night I think is working well, as we're back to 127% LTC profitability from 100% yesterday, while other pools are still down (Waffle stats page show today 0.0059 which is 90% LTC).
But you have the option to hold on to the coins you mined to next week or so, by then the price is up and the revenue for this days mining is higher then exchanging right away.
Just set selling price 20 percent higher as current prices, and your mining returns are 20 percent higher
