JC, I was in the same position several years ago, and tried several different saddles. The saddle that fit me best, and most of the backs I have put it on, is a McCall Northwest Wade. Plenty comfortable for all day rides, and with bucking rolls has worked great for starting/riding young horses.
Also, has worked real well for rough country riding.
I can't say much about the roping though, as I've used mine mostly for the above and ponying young horses, and riding in working cowhorse events.
