Boy, that's a wide array of choices. The S & B's are great. Love the flashdot but they are very $. I like Kahles CSX and Meopta also...alot. IOR's have a good following and supposedly great glass, but I've never seen one up close. Valuewise, the Big Sky or 4200 are probably sound choices. The Trijicon may be a sleeper. Their new reticle choices are superior (IMO) to the old triangle. It has good glass and illuminates without batteries. That just may be the ticket to success. If it were my choice I believe I may try the Trijicon.
