Good LAG Spot or Just Chip Spewing?

[JFB37]

5/10 live at a club. Two limpers, CO makes it 35 (he's a LAG and a bully, means little), Hero calls on the button
with 6 [img]/images/graemlins/diamond.gif[/img]5 [img]/images/graemlins/heart.gif[/img]. Rock in BB makes it 105, limpers fold, CO calls, Hero calls.

Flop: 4 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/club.gif[/img]

Rock leads for $300, CO folds, Hero calls.

Turn: 4 [img]/images/graemlins/diamond.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/club.gif[/img]

Rock pushes, Hero calls.

Hero's original call of the CO's raise was on the theory that the CO could have anything and that the limpers would probably call to make a nice sized pot. The BB's re-raise changed everything. Hero's overcall of the BB's re-raise was on the basis that it was only 70 more into a 255 pot and it was almost certain that BB had a big pair. Clever or stupid?

How about on the flop? Nobody folds, do they? Issue, I think, is call or push. BB might get away from an overpair with a push (and say something about Hero's flopped set) but is just calling too risky as it might lead to a tough decision if, say, a A or K hits on the turn.
