I've been pondering that question on this Fox AE that's 28" F/M choked. I've decided to leave it alone and use it for what it is. I shoot sporting clays and skeet with it and figure it's only about a 5-8% handicap to have the tight chokes. So, as part of my enjoyment, I like the idea that it's choked as it was built. But, I have no quarrel with someone that wants to open one up. Just be sure you're getting what you think you're getting. There may not be as much difference in your scores or bag as you might think. I see so many old doubles that have had the chokes taken out to skt/skt or even cylinder bore. I can find a use for cylinder but I would prefer to have at least one tight barrel of Mod or tighter. One of my doubles has a skt/cyl arrangement and I really don't use it much. It's fine on the skeet field, but limited with the open choked second barrel in the field for my hunting.
