GL man. Doing pretty much the same thing here. I too thought the idea of playing the lowest micros was silly, but when I looked at my game, and my approach to the game... brm, game selection... occasional tiltiness etc. I realized I really had a lot to work on to be consistantly profitable. It makes sense to work on these things and reconstruct a solid foundation at the bottom using agood BRM.
SO doing a personal challenge is a great idea. I am focusing on showing a profit and doing the things required to do so. The chips are just a way to keep score. If the challenge is successful, we will progress to higher limits while being properly rolled and hopefully in 6 months or so be ahead of where we would be if we just continued doing what we have always done..
So you are not alone.

Best of luck and keep us posted with your progress!
