I'm not really sure I understand why a sxs would be at an inherent disadvantage, even with regards to precision on long crossers. When I look down the barrels of mine, all I see is a bead. I don't see two barrels with a bead in the middle, all I see is a bead, especially so when I'm shooting and concentrating on the target. I'm not discounting anything anyone is saying regarding o/u's, because I'm not a competition shooter, just a hunter and regular skeet shooter, but I'm not sure I totally buy it either. I'm probably wrong, but there's my two cents, fwiw.
