I'm playing the exact same stakes right now on stars just grinding for MTTs. Very tight and very aggressive seems to dominate these stakes still.

My VP$IP is 16% at .25/.50, PFR at 8. The best rule of thumb I've had for these stakes is always take control of the hand, if you're playing AKo and throw out a 4x raise and get reraised I'll reraise them again to see where I stand, if he just calls, on the flop I'm in control and he's got "AMERICAN AIRLINES ONO!" passing through his head. If I catch TPTK I'll raise and reraise here again, if I lose control of the hand, or he finally tips his hand by overraising then I get out.

I think your comment on follow up bets is a very bad observation. Follow up bets here are 80% effective for me doing 3/4s of pot with a 4x preflop. It also gets me paid on my real hands (which is way better than a small pot.). I do avoid it more than three handed though unless I have a godlike image going or I see a couple of autochecks.
