Tried the link and got "Server not found" message, so cannot
comment to which you referred.
A few years ago I got the Athlon Talos. The glass was just as
clear as my Vortex Viper. After that, I was looking for a scope
that would withstand the recoil of a smokeless muzzle loader.
After an email exchange with Athlon, I got the Athlon Argos. The
glass was actually more clear than the Viper and I have been
very pleased with it. And yes, it is heavy, however, that just
adds a little more to recoil reduction.
OK, by going to the Midway site and typing in the numbers, the
Talos came up. That's the same one I have (with illuminated
reticle). Don't know which Vortex you are considering, but I
can say that the glass on my Talos is just as clear as that on
my Viper.
