Thanks for the replies
A bit more info on my plans.
I like playing multi table SNG, i have positive ROI from sharkscope. (ROI 15% all SNG's 100%on 45 players or more) So I intend to concentrate on these larger games. I hope to play about 20-30 a week. starting at under £5 (stars $4.40 and $2.20 turbo)

The lost bankrolls went as follows. Start with around $200 play $.05/.10 and start to win. Generally get to $800 having moved up a couple of levels. I used a max5%of BR rule .
Then loose all the money going down the levels back to $200. I did this several times, mostly from bad play and going tilty when on a bad run. I dont suffer the same problems on SNGs.
