NL2 - 99 UGT. Too strong on flopped set?

[You're No Daisy]

SB is 77/21/4.7 and had over $7.00 at one point and is donking off his chips left, right, and center.
MP is 60/10.5/0.50 and is pretty much a station

I am running at 16/12/10 for this session and not many of my c-bets have been called. I'm wondering if my flop line was too strong against these two villains. My typical line for when I hit a set and see two of the same suit on the flop, is to pot the flop (or close to it).

Too strong here? I was thinking of only raising to $0.08 but that would give anyone drawing to a flush the proper odds to call. I thought $0.20 would be perfect (about 2/3 of the pot).

As always, I am grateful for all your comments/criticism.
