He's probably referring to me most of the time since we've been hunting/shooting partners for many years now.
I also like to apply reticles in the field for LR shooting applications. I also prefer a line stadia for more precise aiming points, but the dots r also useful enuf--especially if your goal is big game mostly. If i were setting it up i'd go for the custom dot setup that matches the trajectory of the load u will be using. The reason is that when it's set up for the conditions u will be shooting/hunting in most of the time it will be the fastest, most intuitive system that requires the least attention to detail when using it. It doesn't make any difference what reticle u are using your zeros will change with air density changes (BP, and temp.), so u may as well get a "std." that's easy to use. When u get the reticle ask Leupold to send u a schematic of it with reticle subtension stats, so that when u change loads or guns u can simply adapt the reticle to the new trajectory by running the ballistics program for the new load, and matching the drop in MOA to the reticle subtensions in MOA.
The best way to approach this is to learn the reticle subtension vs. magnification vs. trajectory systems for LR shooting. Once u understand all these concepts it will turn a very bright light on.
