Over my first 1000 hands at 5nl I'm running 16/6, but most of the times I'm investing is in the BB where I see 66% of flops due to just checking. I'm happy with my play so far but I'm wondering if I'm almost playing too tight at this level. I'm finding that at some tables when I loosen my starting requirements my profits increase. So far I'm 5.3BB/100 hands up so I'm happy with the results so far.

Just keep going I guess? My strategy is slow bankroll building and eventually to move up to 10nl once I get 20 buyins.
