Setup determines what choke and load work best, or worst. I like target loads rather than cheapos, and that means I can ease up on chokes.
The choke I use most is LM. Usually paired with either Mod or IC, depending on setup.
The last shoot I did was more of a hunt, and I used a 20 ga O/U with Mod/Full.
Shots were more or less crossers with a few quartering in. Longest hit was about 35 yards.
I'd urge you to take along a few tubes, if your gun is set up for them, and try Mod or LM first.
HTH....
