It is not too untypical for a binocular to have some diopter issues, as the Talon plainly has. However, eye relief is a pretty cut and dried, set by the design sort of thing. Ever had a binocular where you could see the whole field with glasses? I ask because some eye glass wearers can't. As far as I can tell from side by side comparisons, the Talon and the ZEN ED 2 are the same ainmal with different armor. The ED 3 does have a little bit better eye relief than the ED 2, so that may work for you. You may want to look at an 8x version as the eye relief may be different enough to work. An 8x you can use efficiently is a heck of a lot better deal than a 10x that gives you fits. Thge ED 3 7x43 has more eye relief still. 7x is my favorite all around magnification. I hunt the wide open high desert spaces, so don't fall for the better detail "always" comes with a 10x. Better detail comes from a binocular you can use.
I will add that I recently sold my Vortex Razor HD. It was a good enough binocular, but frankly could not distance itself from the ZEN ED 3 or my Kruger Caldera. I figured there was no point in having the $$ in a nearly $1,200 binocular unless it could show something definite in the way of performance.
