I was playing 50NL 6max pre UIGEA and I could run 16/14 and show the same winrate I did playing 30/25

1) I was better post-flop (they were terrible, not saying I'm good)
2) They basically played they're own cards

It doesn't matter if you're tight at 10NL because they're playing their cards, not your image. They might notice you're more aggressive, but they won't relate it to starting hand selection. You can open up and get some experience post flop and reading hands, but opening up (giving action to get action) it won't directly help your win rate at 10NL.

1 exemption is if you have position on a spewy ATM. You can raise almost any 2 for isolation.
