Here's what I would do. Order a fixed power (my choice a Nikon Monarch 4X or 6X) and variable of your choice and compare them side by side under low light conditions. Ask yourself what scope delivers the most useful image under those conditions the fixed or variable. That is what I did with a 4X Monarch I ordered and a Leupold VXIII I currently own at the time (twice the cost and more weight).I kept the Monarch and put it on my "mountain rifle" and sold the Leupold.
