I'm surprised the Leupold looked better than the Zeiss! I thought with the fluoride glass it wouldn't be so.
To the OP, if you don't care about the internal level, scope caps, and throw level you can find great deals on the regular vx-6. According to Leupold the glass is the same and if you have the free dial for the zl version you can use it for the new zl-2 as the scope is capable. The adjustment difference is in the design of the turret. You can also have leupold throw in a new reticle for a little extra.
