2/4 AJs hand.. good line?

[DCIAce]

UTG+1 is LAG (50vpip, 15pfr through 60 hands), MP1 is just horrible (80vpip, 5pfr through 200 hands).

This has become my most used play when I flop a big hand. Bet into field, call and C/R turn if raised, keep hammering if not. Is this a solid line, or am I missing bets by not 3-betting flops and hoping for extra raises later on?

Also, is the pre-flop raise standard? Anyone cap after getting 3-bet by a LAG with someone that will call with literally any two along for the ride?
