Anyone winning with MSS?

I have been playing MSS. Years ago I had was winning on Carbon and Lock poker at low stakes over a decent sample but they ****ed me on my withdrawal so I quit. I am getting back into it now that ACR has good reviews. I was just wondering if MSS is still working. Over 2k hands I am still winning (22 bb/100) but we all know that is a super small sample size and will probably level out. I do not see many MSS players on the tables and wondered if there is a reason for that? Also seems I will have to adjust to play 6 max as I can only get like two 9 max tables at a time. Thoughts?
