JJ in SB multiple limpers

[gvegas]

Blinds 100/200 Hero has 6,600 after posting SB. Average stack around 11,500 early on.

UTG and UTG+1 fold, MP1 calls, MP2 calls, highjack calls and Cutoff calls.

Hero raises to 1,000 with JJ. MP1 calls and MP2 calls, the other 2 fold. Both callers have hero well-covered.

Pot is 3,600. Flop is 6-7-8 rainbow. Hero moves all-in for 5,600.

First off I hate the pre-flop raise to 1K. Too small. If even one of the limpers calls i'm giving any other limper around 3.5 to 1 which prices in small pairs and suited connectors. My question is really about the post flop shove. Outside of a set or flopped straight or 2 pair i know i'm ahead as QQ,KK and AA raise pre-flop. MP1 was a loose calling station and i really wanted to charge him to hit an overcard. I wanted to take the pot down right there and if i bet the pot i'm pretty much committed anyways.

Thoughts?
