I have a vertical Star Track right now (and love it). I checked out the angled version at the ATA, and it looks pretty interesting! I'm going to see if I can buy just the outter "ring" to try it without buying the entire sight.

I will also say one thing about VBG. A buddy of mine had broken all the fiber-optic's off his Star Track last year. Just hunting hard, and wrecked it. Anyway, called VBG, they are fixing it for free - Lifetime Warentee! That sealed the deal for me!
