I've just started shooting skeet and have been given a citori by my grandfather. It uses standard invector chokes. Im on a budget and want a few extended chokes to start with. I can get the carlson sporting chokes for under $30 locally, but I like the look of the fn invector with the ID ring. The fn's are about $5 more but I don't see much about them. Carlsons seem more geared towards port shooting but not much info on the fn. Will I see any real performance difference between the two? I appreciate everyone's help.
