When I had the same questions a couple yrs back, a gentleman here on the forum lived within driving distance, and was kind enough to allow me to "test drive" several different sights, on some very nice wheel-guns. I've had reflex sights, a Bushnell Elite scope, and irons. For what its worth, my super blackhawk hunter now is complete, wearing an ultradot. I didn't care for the scope, due to poor performance at first / last light. The reflex (fastfire) is a good sight, but not as quick on target, or robust as the ultradot. Perhaps you could find some folks near you, that would allow you to share a range session, and see what fits you best.
