FT at 11+1r+1a - range to call a resteal?

[Quercus]

Table has been aggressive. Lots of steals and lots of resteals. Very few flops. Villain in this hand is a winning player who we know very little about. He's not the most aggressive player at the table, and he's not the weakest.

Hero has been stealing and restealing along with the rest of the table and is also not the most aggressive player but also not the most passive.
