I have shot a 30'' for many years and although I have tried a 32'', I personally would not buy one. I found they certainly steady the shot and have great pointability but I found they also slowed me down quite considerably. Whilst at High Lodge the other week, I played around with my 25'' barrels on the 3200 and shot at all the targets throughout the 22 stands. Some were missed and hit when I switched to my wifes 30'' trap gun. This happened on about 4 stands where the scores were much improved whereas with the short barrels, I found myself shooting faster at the targets.
I was quite supprised just how many of the clays were easily broken with the skeet barrels as I have not shot at sporting targets with this type of gun since the very late 70's when many of the competitors were using skeet guns for sporting.
I really believe what goes on in between the ears has a great deal to do with your results just as it always has done.
