great low and flush draw on a paired board PLO8$200

[GaZaZaZa]

I think i know what i should do here but just interested in your guys opinions,

Effective stacks are $120 and i have no real reads on either opponents, but in the 20 minutes ive been playing i havnt seen either of them do anything out of the ordinary, if anything they both have been playing moderatly tight.

i am on the button with 2-3-4-6 2-4 being clubs. Villains are the UTG player and BB both having around the $120 mark in front of them. utg limps, i call sb completes and bb checks.

Flop comes a-a-6 with two clubs BB bets pot, utg re-pots, my move is???

Also would it make a difference if the board was a-a-5 instead??
