In the very worst case scenario where your not drawing dead on the flop you would be up against something like A8, KK and TT-22 (except 55), in this case you have exactly 20.9% equity. Since according to the op your up against donks with ridiculous stats you can assume they on average will have worse than this and raise and re-raise the flop for value. BUT i would suggest that if you think there is SIGNIFICANT chance a flop raise will likely fold ALL hands behind you (since you rather be in a multiway pot than heads up with the likely best hand) then a call/3-bet would be best, but this is just dependent on your reads i guess. In any case you have to raise the flop somewhere. the rest seems standard to me.
