Big6x6,
Well, I would have to say that it's a combination of a few things. First, and foremost, the resolution, although good, is not as good as my Elite 4200s, or even Nikon Monarch, or even Zeiss Conquest. Second, the light transmission is also good, but not as good as the others. Third, they are just very heavy and bulky (they have 30mm tubes). Fourth, I'm not to crazy about the knob on the bottom side of the scopes that stick out - even though mine doesn't come with the posi-lock. Fifth, they just seem to scratch easier than the other scopes I mentioned. Heck, I have put my other scopes through the ringer and never a scratch, but I do have one on my BDs, and I'm not happy about that.
