Boo, I'd let you play with both if you were near.
The warm fuzzy might be what 6oz of a Nightforce SHV F1 gets you.
I don't believe Maven is at any risk of folding up shop; I think they are very very healthy. I do understand your concern about the product line possibly changing and equate that possibility to the Bushnell LRTS/LRHS lines, or any scope from Nikon. Ask
@TheCougar about his recent Bushnell experience.
I have one RS1.2 that I will probably hunt with if I snag a rifle tag, four SHV F1s now, and a 10x SFWA side focus that's on the kid's rimfire, with an additional RS1.2 on loan to
@Ucsdryder. With pic rails on all rifles I can switch out a potential problem child in a few minutes and be rezeroed quicker than most oil changes. I genuinely do like the SHVs and really only ended up with the Mavens because the opportunity to review fell in my lap.
With that luxury of being happy scope flush, I don't have your same concerns. If that were weighing on me, the NF is the easy button of "durability" but (subjectively) may not be the most ideal reticle/zero set/weight. The Maven (subjectively) may be more ideal in those areas and that's what I would make my decision on.
If I had a rifle and a scope to procure I might feel safer with the NF and not NEED to worry about my scope in functional fashion. I might at some point get a hankering for lighter or a "better" reticle down the road as a WANT.
I too sent a 6x SWFA back for being very broken and that's how I ended up with the 10x side focus. My brother got restationed here locally and just bought a house off base so now he has his own rifle. He put a 10x side focus SWFA on it knowing he has my stuff as a parachute if it goes wonky.
If I were spending your money, I'd look at if you have an "old reliable" or not (or access to one) that can you have you back in the game within a day and let that make my decision. I THINK the RS1.2 has a really good chance of being described that way in a few years, but it still a rookie.
