TPWK in BB - how do I handle this flop?

[Langerz]

Reads - UTG+1 is pretty new but seems laggy.
BT is an almost perfect fish that stacked off recently and min rebought.

I seem to find myself in spots like this a lot and go back and forth between donking and c/calling. I usually tend toward donking since c/calling seems weak. I want to bet out and protect my hand. The problem is if I get raised I'm probably in trouble but also have a big enough pot I may not be able to get away. If UTG+1 calls the fish is getting 8.5:1 and can call most pieces. I'm not folding though and c/c seems weak. (c/r just amplifies the problems with donking) Curious on the correct line here.

Also add comments with on how this changes if button has a reasonable stack since it is more common and probably more interesting.
