I shoot a double, also, and I can tell you that nothing feels (or looks) better in your hands than a slim little English-stocked 20-bore that weighs about 5 1/2 lbs. Mine is a sidelock with hand-detachable locks and a pretty nice piece of wood.
I must admit that I feel pretty darn good when I uncase it and let my best setter out of the rig for a day' s hunting or a field trial. Everyone who is around gives a knowing nod and an envious smile...you can almost see the wheels turning in their heads trying to figure out how they can justify it to their wives.
