I guess we could compare OU vs sxs to aluminum vs wooden bats. Aluminum has a bunch of advantages . . . but they still use wood in MLB. I expect part tradition, and part the fact that the top pros are willing to challenge themselves with an "inferior" piece of equipment.

There are relatively few "full race" sxs target guns out there. Too many shooters these days have never used them, so they're going to stick with OU's. In the same way, a lot of OU's now being used in driven shooting in the UK. Mainly because that's what those shooters learned on. And even the really good sxs shooters will advise that if you're after the really high birds, you're better off with an OU. Yet they continue to shoot sxs. Maybe because the challenge is more important to them than the score.

The shooting games all started as off season practice for hunting. Especially true of skeet (invented by grouse hunters) and sporting clays (originally called hunters' clays in this country). The focus then shifts to score. Let's see . . . let's allow skeet shooters to mount the gun before calling for the bird. And no variable delay. Voila . . . lots more 100 straights. But since you don't premount when you walk in on a point, and you never know exactly when the bird is going to flush, it's no longer as valuable as practice for bird hunting as were the original rules.
