I've been mining solo since the first 2 min release (stopped for 2 days and came back). I only have 700khs rig and am able to mine 10 blocks/5 hours. If you have 700+khs, I'd recommend you mine solo guys, more profitable, and 0% fees.

~200 blocks in just about 2 days. Plus if you solo mine you sometimes get blocks worth 500 (3 of those for me) to yourself instead of hoping they get split properly
