SB 76o, spewy?

[q16]

Live 3/6. ~6 limpers, I complete 7 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/heart.gif[/img] from the SB (normally I'd pass, but I'd just sat down and won a nice pot in the BB, and wanted to seem unnitty). BB checks.

Flop 8 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/diamond.gif[/img] 5 [img]/images/graemlins/spade.gif[/img]

I bet, 5 callers.

Turn 6 [img]/images/graemlins/club.gif[/img]

I bet, 2 callers, button (laggy, bright) raises, I 3-bet, folds back around to button who calls.

River 8 [img]/images/graemlins/heart.gif[/img] . I check.

Preflop is probably a small leak. Are the flop/turn bets spew? Does anyone c/r either street?
