First I do not own an o/u rifle, but I shoot an o/u shotgun, and I love it and would love to have an o/u rifle!
That being said, it seems to me that if you can move past the “mystic” of the s/s double, than their should be no problem using an o/u. I will admit that I like the look of the s/s and when I think of classic doubles s/s is the way to go. But at the end of the day it’s all about 1. What feels good, and 2. You can afford. O/u’s are usually cheaper. If possible, I would go for the double trigger model.
