Personally I don't care for NF weight. They are a beautiful piece of work no doubt. If its a dedicated range gun, great, but guns get heavy fast in the field. Then there is the cost... For the difference I'd rather be half way to my next gun.
There are a few zeiss on that page for ~1k that will do everything you want it to do. I don't think 15x is underscoped esp if it is clear glass. Yes higher power is nice, but not necessary. For my money sightron moa reticle does everything I want it to do. I've out shot plenty of NF's on the fclass line.. No matter how good of scope you have you still have have to squeeze the trigger.
I just ordered a sightron big sky 6.5-20x50 moa for my 300wm build, should be here next week. I was looking very hard at huskemaw, vortex hlr, and leupolds.. and anything else anyone mentioned I considered, but none had the value, weight, and preferred reticle style the sightron offered. Don't get me wrong, I'm not saying sightron is for everyone, but for my practical uses I think the nf's are overkill.. weight and price.
