Teach e to fold bottom set

Villian here is a huge nit. 7.8/4.7/6.00 64 hands.

I really wanted to fold, but then I remembered that I cannot fold sets. I am not really familiar with his postflop play but I don't think anybody but a donk shoves here with A [img]/images/graemlins/diamond.gif[/img] Ax or A [img]/images/graemlins/diamond.gif[/img] Kx

Crying call or easy fold?
