I like 12s and 20s but wouldn't most model 21s weigh as much as a light 12?
I shoot a 1100 fps 7/8 ounce load in my 12s and they're a pleasure to shoot. I see no need to go to smaller gauges that weigh the same as a larger gauge. I really don't see the need for the 28 either unless it weighs less than six pounds and I wonder if less than that is just getting too light to shoot well anyway.
Ultimatly, the trick is to put your money into what you want. Owning guns if supposed to be fun. Talking and writing about it's fun too, but the thing to do is buy what you want and enjoy it.
