You guys should realy check out these boards. They are insanely awesome in my opinion. They're made out of aluminum. I kinda want one now. I dont know how much they are but they are made to order. http://www.threesixdownhill.com/shop/
Yeah I've seen some of their stuff on reddit, I've always thought that itd suck to get your foot stuck in one of the holes during a session, and wiping out. Not gonna buy one, but its a very interesting concept!
