HU PLO8 sng Preflop All in Quesion

[PLO8FaceKilla]

I'm trying to fine tune my hu sng plo8 game...
I keep running into one spot though where im stumped.

When i raise on the button with A34J or A248 or anything of similar strength, sometimes i get reraised... unless i have AA, ive been just calling the reraise, seing the flop, and then making a decision. Now if the blinds are high, then i obviously push all in.

So several times i have to fold since i miss. and my opponent will bet all in, since it's around the size of the pot and he's committed... i feel like i can outplay most players, and ill play it unless i completely miss the flop but i feel i might be making a mistake.

should i just be re-raising all-in with these hands?
should i just reraise all in w/ A2xx and AAxx?
