I think everyone deals with this topic. I had in order: 10x razor, 10x slc, 10x el sv, 12x nl, 15x slc hd, sold them all, regretted selling the 15's, and I for whatever reason wasn't wowed by the nl's. I now have 10x el range ta and 15x meoptas and prefer to pack the 15's. I'm the minority I guess that likes 15's on my chest, they're just so much better on a tripod and everything kinda sucks hand holding anyway. 15's still work enough hand holding to get you by to your next tripod location and you can still spot game hand holding 15's.
