Trap Shooting

[Mil Dot]

I have my daughter hooked up with Colorado Youth Outdoors and they intend on doing some trap shooting. I haven't shot trap in years, skeet and sporting clays but not trap. She'll be using a O/U 20ga and a recommendation for chokes woould be appreciated. I was thinking an Imp Cyl up and a Mod on the bottom. Of course, I can just change out to suit but would like to get your input.
