Hi,
I believe the largest guage that handles they way you like it, the better off you will be. I like a light 12 about 6lb 4-8oz with 28" tubes & fit well, my next favorite would be a 16ga about 6lbs with 28" tubes. I think the 28 is a novalty that I would like to have for easier pen raised birds but I really will be better off with a 12 or 16. Now Bill G. has one beatiful A & S 28ga that I lust for.
