Sometimes I am really stumped by bet sizing. Here's an example from today.

Both guys look pretty reggy, not much info as only recently joined table.

I think pre and flop are both pretty std. Now, when I turn the flush, I get confused about optimal bet sizing. There's $9.17 behind in the effective stack ott. If I bet $2.20 here, that leaves $6.97 to shove into a river pot of $6.70. I don't think twice before polarising my betting against fish, however against more reggy opponents I try to balance my range a little - should this even be a concern in this spot?
