Jeff K, I would have to agree with CG. The extra weight of the LX left me yearning for my Mathews Z-light at the end of the day. I have already packed my bow in 5 miles off the main trail head. Each morning it takes about 2 hrs of walking in the dark to get to where the elk hang out from where I camp at. When you walk and stalk from sun up to sun down in elk country a few ounces are noticible by the end of the day. The only time I don't think that it would be noticible is when it is strapped to a 100 lb. pack of elk meat. I use my LX for short hunts and for the 3-D range. When I go on the extreme hunts my Z-light is at my side.
