Bet/Fold or Check/Fold

[toss]

I open raise 77 from UTG+2, Loose Donkey coldcalls, Loose BB calls. 3 to the flop for 6.5 SBs.

Flop J89 two spades, I have a spade.

BB checks, I think about checking because the Loose Donkey is very often going to raise here with a draw, a pair, and nothing. He's also going to call a bunch and put me in a tough spot on the turn. BB is also calling a lot. I decide checking is too weak so I bet. Good bet Bad bet?
