Welcome
I hope you have read the bankroll management thread!
For me i dont mind 3 tabling for 10% my br, i think its fine. Although, if you lose 2 stacks i guess you have to call it a day. Probably, you only want to be 2 tabling and never having more than 5% o your bankroll on the table at any one time. But, there will be others who wont think it too bad that you 3 table for 10%.
I dont see why its to bad, althoughi think id be trying to move up if i have the bankroll rather than trying to multi table.
