$25 NL 6-max: Light 4-bet, Ship this flop?

Villain is a 35/35 or so over about 20 hands. He seems pretty laggy, and has raised the 2 buttons I've seen him play so far. He's been 3-bet light by another reg, and folded.

I like to 4-bet/3-bet a lot early against unknowns, and this seemed like a pretty good flop to ship since I have ~24% equity vs. AK, JJ, ect. Not to mention that he flatted my 4-bet out of position (wtf) so he's either REALLY strong or REALLY weak.

Thoughts on my line as a whole?

=======================================
$25 effective stacks

Hero is dealt on the button.

3 Folds, Hero raises to $1.00, SB folds, BB 3-bets to $3.50, Hero 4-bets to $9.00, BB calls $9.00.

Potsize = $18.10, Hero has $16.00 behind.

Flop:

Villain checks, Hero shoves for $16.00

I like to light 12-bet all in NL25. I think your game plan here doesnt fit to NL25, because the limit is low and in that limit its not useful to make tricky moves. You raise preflop to 1.00 on the button and LAG 3-bets OOP. He could really have a hand there or he might be restealing, but I'd personally(donk as i am) would let this go. mabye im just too tight, but i dont like to get involved with Q3 in big pot where i have been 3-betted(Lag or not, doesnt matter, I'd get out of there).

Dude you continue to have ballz of steel. If you said "I absolutely know my opponent will fold" on the flop (not sure how you would know that) then I love this "bluffy maniac" line. Otherwise you are just out of control...

Well, if you're going to 4bet with Q3s, I see no problem with the post flop shove.

Do you just love variance? Do you have variance insurance? Actually you may not want to let Zach see this hand or he may deem you to be uninsurable.

don't hate a flop shove. you probably have 5 1/2 outs if called and a decent part of his range can't really continue on this board. I doubt a guy like this is very strong here, ie. flatting with AA or AK etc (because with no history and at micro stakes he simply can't be thinking you are 4 bet bluffing here..ergo there is no point trying to let you hang yourself on the flop).

That said, why you would ever try to 4 bet light in 25nl vs a maniac-type player and get yourself in this situation is absolutely beyond my comprehension.
