Villain is loose-aggro 38/20/70%steal/6.3%3b/2AF/38%AggFreq over 66 hands and 50% fold to 3b (4 hands).

What does he min-checkraises the flop with, really is the question. After the 3b preflop, would a range of {AA,QQ,99,JTs,AJo+} be reasonable or too optimistic?

I have 41% equity against this range.

What now?
