 Yeah, no, I usually, I think the most popular are those six to nine, because if you're hunting out of like a box blind, sometimes you need a shorter one. But every once in a while, if you're guiding the mountains or whatever, and you're going to be on some rocks, sometimes you do need a little more. But anything longer than that, you really need to have like a common thing you're shooting off of, and you go, well, yep, I need 15 inches to shoot off what I shoot off of. So, yeah, start with the smaller ones. That's usually what most people end up with.
