personally, just for handling considerations, I'd leave the barrels a bit heavier (not full-blown bull-barrel heavy, but definitely heavier than average!). I find that a bit more weight out front in a double is a good thing for balance and consistency in swing.... case in point, a 12ga, 20" S/S is VERY hard to really "even out" where a 30" 12ga o/u is cake (most 28s are prefect)... anyway, you get my point... that weight helps smooth the movements...
