According to pokerstove, this is 21% pf

66+,A4s+,K7s+,Q9s+,J9s+,T9s,A9o+,KTo+,QTo+,JTo

Now i'm going to knock it down to what i think would bet and call your raise here, tell me if you disagree with my thinking.

A4s+,910s,66+

Now putting your hand up till the turn into pokerstove
equity win tie pots won pots tied
Hand 0: 26.023% 26.02% 00.00% 687 0.00 { KcJc }
Hand 1: 73.977% 73.98% 00.00% 1953 0.00 { 66+, AQs, ATs-A9s, A7s-A6s, A4s, T9s }

Now things that could change this are if you've been increasingly aggro on the flop, I generally just call and reevaluate on the turn based on card/betting.

In the end though, i end up check/folding here most of the time as calling any bet you're just hoping for a club the majority of the time and that might not even be good.
