Hmmm... I don't get that. Do you suggest leading?

Using more detailed stats:
His 3-bet to an EP raise is 1.4% which makes sense with 2% overall so QQ+,AKs - seeing that he has never 3-bet even AKs from all the hands I have in his db I would guess probably more likely QQ+. With 60% c-bet I don't see ho I could possibly have more than 30% equity on that flop.
Stats are over 3k hands so there's not too much room for statistical error.

About the set-mining. I'm not opening less than 55 from UTG+1 9-handed, but just theoretically I don't see how calling with TT is much different from calling with 44 in this case. No matter how you interpret his range, he has to be very strong and I'm potentially getting 16:1 when I hit the flop.
