If I were prince for a day, I would buy the Perazzi 32in SxS I got to shoot the other day on sporting. It was a SC gun and around 8.5pounds, but it balanced. Would also have made a pretty good pass shooting Dove shotgun.
Only $18,000 and it was plane Jane.
On the whole, long and lean barrels for LW field guns, which are hard to find. Heavier the shotgun makes shorter barrels almost a necessity. 26in pumps and semis are pretty much the equivalent of 32's when compared to O/U's when referencing sighting plane.
Most SC shooters are at 32in for O/U's and 28 for semi-autos, but as mentioned the Semi's will have a corresponding longer sighting plane due to 5inches or so of receiver.
