NL200$ Omaha8 turn play?

in this hand i thought a few seconds on the turn! the reason was, that i was very sure that one of my opponents must have A2XX like me so i decided to flatcall, because i knew that tose fishy guys are capable of pushing a lot of topset type of hands on the river and i was sure that the money will go all in on the river anyway
--> if i raise the turn hard, i can play with open cards, because they will know what exactly i have A2XX and this might scare away any worser hands.

any thoughts?
