Re: shorter barrels and chokes. Assuming you have 2 barrels, one 18.5" (legal min) and one 30", and both are choked the same, the difference between the two is removed if you stand 11.5" closer when shooting the short barrel one. However, longer barrel will be easier to follow through with and track the clay, and may have less felt recoil.

For basic trap shooting, a pump 12ga. with screw in choke (or fixed choke of modified or full) will be fine, or even a single shot. I'd prefer a longer barrel - 28".

For skeet shooting, you will need to be able to shoot doubles, so single shots are out, and you gotta be fast on the pump if you use one of them (I did for years, had no issues). Skeet is a closer game, so you'll want more open chokes.

My skeet (and trap for that matter) gun is now a Fausti 20ga over/under with screw in chokes (sold my AK just before election to pay for it). Came with 1 each of full, modified, and improved cylinder, I bought a second set of each. When shooting skeet I always use IC in both barrels, for trap I have one with full and one with modified and will change which I use based on wind, how I am shooting that day, etc.
