+2 owned a number and never regretted it.

Burris FFII would be another option.

I have had no experience with Nikons under the monarch & none with vortex or sightron, however I see/hear guys who like these.

Use to be a leupold guy but lost me when they went to the VX III from the vari x III (a very solid scope), no longer worth the price IMHO. Been buying Zeiss Conquests since my less then desirable VX III purchase, 5 so far..I like em'!
