Best of luck- doing well so far!
I'm not much of a cash game player, so tried something similar with sngs- the $1 turbo 45 player sngs are just as easy as most freerolls
played 500 of them and made $230 (plus cleared $50 free cash), so am now playing another 500 to see if I can do better, having deposited $50 (so am clearing another $50 bonus)
Effectively the $50 cash/ bonus pays for the $0.10 fee - so it's basically rake-free.
I find cash games too stressful- when someone hits that 2/3 outer on the river then losing a nice stack thats taken hours to build up can drive me mad, whereas in a $1 sng all you've lost is the buyin.
getting to $10k would be a great achievement from $50 - I'm dreaming of getting to $1k!
Best of luck anyway and I'll try and follow your progress
