Lots of testing over the past year with Litecoinpool, prohashing, hashtocoins etc. If you want a pool you can set and forget, I have found Litecoinpool.org to be the most stable and profitable if you’re sticking with LTC as final payout. I was really attracted to prohasing, but the constant coin switching delays and high fees make it not worth it. Some testing had prohashing ahead a bit, but overall litecoinpool wins in my book. Unless you have a lot of hash power, the LTC generated is negligible enough to not have to monitor 24/7.
