It's a good thing you got the dangler! I have a hard time unsheathing my B-11 in a mashed cat sheath with a teclock. It's much easier with a dangler & leg straps.

I still stand by the fact that my Rainwalker split drop loop w/ leg strap sheaths are my favorite setup. They carry so well and angle the the handle outward a bit so that the sheath is away from your leg. It also places the handle in a better position so when you draw the blade, you're not drawing it straight up, you're drawing it outward at a slight angle, making it a bit easier to unsheath a long blade. Hopefully that makes sense. If not, I can take some pictures. It's a subtle touch, but it goes a long way.

I am really excited to get my AZWelke exposed spine sheath because AZWelke makes an excellent sheath and I've never had an exposed spine.

I think that Mashed Cat makes a great sheaths, as well. I've never taken the plunge on a Buy Brown sheath.
