If the T and H-1s are as good as my 15 year-old Aimpoint, and no reason to suspect they aren't, they look like winners and I have drooled over them for as long as they've been available. The main difference between the two is submersible depth and cost. I'd go with the cheaper which is still expensive. I've got a couple of Trijicon Reflex sights, the old Aimpoint and FFIIIs. I like the size, cost and weight of the FFIII compared with my other dot systems. I'll see how they hold up this season. However, the new Trijicon RMR system seems to beat all. Self-illuminating with fiber optics and tritium lamp, it appears to be the size of the FFIIIs. It, too, is expensive. Gil
