Hey I recently won a freeroll and have been playing 2nl to grind up some kind of roll. I'm wondering what BR you guys would recomend for moving up to 5nl, keeping in mind i cannot redeposit. 2nl is easy money, but its getting really boring because even though so far i am maintaining over 50 PTBB/100 i feel i am not improving at all as any kind of play is rewarded against a field of 100% donks. Would i be safe moving up at $100?

Thanks in advance
