A pretty faithful recreation of the original. I briefly considered doing the Night Force version because red often seems out of place on a JOE, but I decided it just works with Crazylegs. A lot of folks around the web have been doing him lately, and I took bits of different recipes and made him my own. One thing I didn't see anyone do was use the Snow Serpent harness, and I was worried it wouldn't fit, but it ended up being perfect.
