RE: LEUPOLD vxIII or vxII ??????????
I agree with James of the 2 I'd opt for the VXII.
Though I'd check out the Zeiss Conquest for comparison sake. To my eye it is superior to the VXIII and cost less or similar depending on the model of interest.
Nikon Monarch or Bushnell Elites would also be worth comparing to the leupold VXII.
