My sevens good?

[Roy6]

Preflop 3-bettor is very aggro preflop. He iso 3-bets AJo, 3-bets 44 in the BB in a multiway pot.
Postflop he tends to calm down, although I couldn't see a lot of his cards.
The other player (UTG) is a 65% VPIP fish who will chase all the way and makes very bad bluffs HU occasionally.

Your plan for this hand please..
