They should begin with the 28, the best of the lot.

And I wonder if an alloy-receivered Red Label would work out OK? I have shot a Beretta O/U with an alloy receiver and found it very usable, at least the 28" barreled one I shot. Swung OK and carried VERY well. The 12 and 20 Red Labels have always had a "weight problem" for me, at least for upland use.
