Re: Wheels: Metal or Plastic?
I posted a picture during build season of the wheels we were using this year: 
The thread with the picture is here and it has all the information on how we went about fabricating them: http://www.chiefdelphi.com/media/photos/34720
The wheels worked surprisingly well and with a few more tweaks this will be a viable option for us going forward. We may be looking at making a 4 cavity mold so we can pump these out even more quickly. I estimate in one saturday we could have 20+ fully completed wheels done and ready.
As for other wheels I've used in the past, metal (aluminum) has always been our go to wheel because of the stability. We've always made our own wheels so we can control the dimensions that are critical to us and cut down on interfaces (hubs, extra bolts, spacers, etc.)
