The difficulty is continuing to go up. You're not going to keep getting the same gains. You should stick with one of the bigger pools. That's either Ravenminer or Suprnova. Personally I try to not use Suprnova. I never get good hashrates there and I feel like I'm underpaid compared to other pools. Their reporting is shitty and sometimes doesn't update.
I hear the hash rate thing about Suprnova all the time. I wonder what that is. Coin rate has been slightly better for me at Suprnova. I've tried a bunch of the pools over the past two plus months. And every time I find one paying what I expect to get paid, it closes. Too many variables when it comes to pools, you just have to find one that works for you.
But the reporting comment on Suprnova, not sure why you think that. They have more information available than any other pool I've worked with. What don't they have that you are looking for?
Suprnova's reporting isn't historical. I can't see what my hashrates were, my trends, etc. If you've used Nanopool or Ravenminer I prefer their way of showing mining activity. Maybe you can get that with Suprnova and I'm just ignorant?
Suprnova is a rocksolid platform, with lots of pool hash-power so you can easily find and work on blocks. I always keep it configured just in case I want another solution here and there. I mix things up here and there.
