Feedback? Okay, just my two cents.... cool idea but something is not clicking with me. Perhaps if the outer sleeve was just a little bit smaller in diameter so as to not look like a "pig in a blanket" thing. Another thought, wondering what it would look like if you turned the outer sleeve a quarter turn so the slashes were pointing down. And finally.... maybe add another smaller slash section over the exposed inner pipe? or some kind of heat shield. Maybe something with holes or slots? That section looks like exactly where my legs are positioned when sitting at a stop, can just picture burned boots/pants or for those more daring burned flesh if you accidently brushed up against them. Man, I envy you guys, I would love to have the time, equipment/tools and know how to "prototype" stuff all the time. Pop isn't perhaps looking to adopt is he? You know, I never had a brother Brent, hehehe.
