your winrate is 18.6bb/100.  I think you're doing fine.  jesus.

I would assume that you SHOULD be losing in non-sd when facing a 3bet.  In that case villain almost certainly has a tighter and stronger range than you, and villain will likely take the betting lead.  My guess is that you're making up for lots of folding by stacking villains that can't fold their overpair/toppair type stuff against your wraps+FD/trips/sets etc.

If you really think it's a big leak the best suggestion I could make would be to start by folding some of the worst of your range facing the 3bet, and then postflop try to work on realizing your equity either by avoiding difficult b/f spots or by working on your range construction post so that you can have a turn raising range that includes value and bluffs after calling a flop cbet facing a double barrel.

When villains are putting too much money into pots with weak, wide ranges, we should be making most of our money by getting to showdown against them with tighter, stronger ranges/pushing equity edges against them (e.g. 4-betting our strong hands and getting action). Guys over-aggroing aren't the ones we need to beat pre-showdown as your ~20bbs/100 winrate shows.

Don't get me wrong, searching for ways to improve is always good, but the bottom line here is you are crushing these guys so broadly I'd keep doing what you're doing!

Taking the control of match doesn't always mean being the aggressive one.  Sometimes you can just sit back, play solid poker and let those aggro players do all the work to exploit themselves, and that is a much more elegant way of controlling the match.  Think about it, yo. :)
