Check raise good here or costly

[Nairb]

Another 45 man $12 on Stars. CO had been very loose agressive, raising UTG with KQ and betting small all streets without hitting any part of the flop and running about 68/12 over 20 or so hands. BB seemed solid but had been playing a lot of suited cards cheap and I had to put him on a FD with knowing he had shown down a couple of small flushes but had just lost a big pot when CO had called his 4x raise with 10 7 and flopped 2 pair against his KK. I did not want to give him odds to chase the flush but I really thought CO would call my raise. Whats your play here and is the check raise for value with bottom set bad here?
