Care to share your ROI on the 10+1

[1p0kerb0y]

I travel around from website to website, stopping in and playing sngs each site, the 5+5. My ITM is 46% and my ROI is 46%. Admittingly, I only have about 200 SNGs recorded as of right now. But assuming these numbers are prevalent, if I step up to the 10+1 I will need a ROI of 23% to sustain my current win rate. Is this obtainable on the 10+1? Hopefully I could clear 30% to make up for the variance I will encounter with a lower ITM. Is 30% an easy number to obtain in these games? If so, are there any sites that you would recommend I stay away from(because of the tougher games)? Thanks.
