I have and have ran VXII 2-7X33, VXII UL 3-9X33, M8 6X36, and FX3 6X42. The 3-9X33 UL is schit, no eye releif at all and only 1 oz lighter than my 2-7X33 with normal Leupy eye releif. The 6 powers are in a league of their own, they have insane eye releif and come up and center like an extension of your body. If 6X doesn't scare you to run, I'd recommend it.
