When I was shooting a Beretta O/U, I started out with a 686 then changed to a 682. I never made it to the beefier DT but I suspect they would be a true workhorse. International skeet and bunker trap require fast movement to the target and weight would be an issue, so I agree with the Perazzi and even the LW Parcour. For sporting clays, I have never felt handicapped with the additional weight of the K gun. I am almost into the old fart category (hehe), but that may just be an excuse for the K20.
