I like them all for different reasons. We are going to the 28, hence 3 of them, lol. The 28 with an Indian Creek choke and my TSS hand loads are wicked. I don't overstuff the loads and they pattern better. Less pellets, but less waste too. I.5 oz loads are brutal to shoot too. I came up with a 1.25 oz load of TSS 9's that is really good. Both 20's have killed a lot of turkeys. And I was using the 12 when I tripled with my wife and daughter. So I like them all. Can only shoot one at a time so I am going with the Sa-28 to start with.
