AH, no I wouldn't bring all chokes with you...it couldn't hurt just in case you don't like or don't feel confident with the one you're shooting. Shoot a modified...it's the middle ground...it should serve you just fine. By the way, what kind of gun are you shooting??

I would have suggested trap b/c that is more of a typical pen-raised pheasant scenario but trap just doesn't challenge you enough, IMO. And, birds are birds, they have a mind of their own (pen-raised or wild), they'll flush right into your face or away from you like a trap target. Skeet's the way to go when talking about practice...give's you plenty of angles at likely distances.

Sporting Clays can be beneficial though. There have been times where I'm in a slump on the skeet field and resort to SC in order to relax a bit and get away from 'the basics.' However the basics simply cannot be ingored on SC. I shoot for fun but take skeet a little more serious than other courses. When I shoot SC, I take it seriously but I always notice I'm a little more relaxed than usually...probably b/c I feel like it's a breather from the skeet fields, haha. But, in all honesty, it can help b/c you can beswinging on targets with bigger leads, smaller targets, obstacles mixed in and when you go back to the skeet fields it seems like a piece of cake.

I completely strayed off topic...sorry AH...hopefully some of my rambling will help.
