I would opt for the old long tom full choke bbl. Tightest shoooting gun I have is an old mosturd w/a 30" fixed full choke. It's smite'd a tom with 2oz of #6's at a long 47 paces (I thought he was closer.....)
The last 2 toms I've whacked were with 3" #5 heavy13's. With My double I'd have 7 1/2's with an IC choke in the bottom tube incase they got within spit'in distance, and #5 H13 with a cabelas heavy shot full in the top tube.
Brother in law wants to split the cost on some dif shells to do some pattern testing, so I'll prob carry roman candles in 5 or 6's this spring.
Like Dd1 said, it's all about pattern density - hitting them hard.
