I believe you have the Savage Fox? Heavy but solid gun. My favorite knock about SxS was a Savage 311. I've had a good number of SxS's and a few O/U. Don't care for the O/U's. Got rid of my last one two yearts ago. Very nice gun, Browning Citori in 20ga but like the feel of SxS's better. Most people using doubles like the O/U's and I think it's the single sight plane. If your in a duck blind, the SxS would have an definate advantage in that it doesn't need to open as far to get the shells out. A big plus for both for me is I carry my gun open and with the chambers MTY. I am more comfortable that way and have plenty of time to load, I use pointing dogs and do not shoot birds I walk up.
I'll say this about O/U's, I'd rather one of them than most any modern pump or auto. There are some very nice one's around. BTW, this is just my opinion, other's are gonna like the O/U's better and you should consider their opinion even if it is wrong! lol
