I built an 8500.00 BR on carbon from 8$ freeroll money that I earned on PO. It can be done. I played sngs to keep my BR going up and played a couple small MTT's. I cashed a couple and went from there still supplementing my BR with sng's but I changed to hyper turbos. The main thing when you have a small roll is to be on your A game. Don't try and roll up if you only kinda feel like playing.
