RE: Upgrading scopes
If you are willing to spend the money, the Zeiss Conquest is the best of the lot. If I had to choose from there, I would go with the new Nikon Monarch. I have looked through both, and I got a great deal on the Nikons, so it was a no brainer.... I bought 2. If I had not gotten the deal, I would have gone with the Zeiss.
