I started 2nl and $1 MTTs with $50. I moved up to 5nl and stayed with the same MTTs when I got to $100. Then 10nl and $2 MTTs when I got to $200. I have a higher BR right now, but I'm still at 10nl, and I try not to buy into a MTT higher than $3 but sometimes I will play a $5. I'm serious about my BRM, so I play according to it because I would rather go back to 2nl and play with my own money than start over again. BRM really works if you use it. GL to you
