After purchasing new glass and spending a little more money on higher quality on my 15x's, now I am looking at replacing my 8x and wanted thoughts if anyone has experience with the difference between 42 & 56 for treestand hunting (so I imagine weight/portably is not an issue). Thoughts on what may be more advantageous. I was thinking the 56 just because a lot of glassing in timber is low light due to a thick canopy.
