I've got NXS scopes with the NP-1, NP-R1 and NP-R2 reticles.
If I had to pick one for a predator hunting rig, the NP-1 wins, hands down. I've used these three both day & night, and the NP-1 is tops. Here's my reasoning...
The 3 post duplex style 'floating' in the center of your f.o.v. allows for quick target acquision, yet doesn't obstruct your sight picture. The outer bars are just heavy enough to get your attention, but don't get in the way like a traditional #4 reticle would on smaller game...
The fine inner x hairs are great for small targets at longer range. No problem holding on a woodchuck's melon @ 500yds on max power /ubbthreads/images/graemlins/smile.gif
The only thing I like better about the R1 or R2 reticles, is that I can quickly hold into the wind more precisely with them due to the horizontal stadia. I say this because on longer shots, I like to dial for elevation and hold over for wind (since its always changing). The R1 & R2 are better suited for the unoccasional long poke on max power. Admittedly, this doesn't happen often while calling though, hence my overall preference for the NP-1...
For everyday hunting, the 'clean look' and simplicity of the NP-1 rocks. Especially if you sight in for MBPR with a flat shooting rifle and therefore don't need to rely on reticle subtensions to hit your target inside of 300yds. Just hold on fur & squeeze...
As for the NP-2DD, I think the center dot would take some getting used to, but I could learn to like it. That tiny little aiming dot would probably be ideal for prairie doggin' too...
Side note with reference to night shooting:
The 1-4X & 2.5-10X NXS Compacts have an exposed rheostat illumination knob on the the left side. So dialing the right amount of brightness into the reticle at night is a piece of cake. Keep in mind though, on the 3.5-15X and larger, that left turret is the AO focus. Adjusting for brightness is a little more complicated and not as 'field friendly' on the bigger boys...
Either way you go, NXS scopes are AWESOME...
