The new SWD bike is around 12#, not 9. A good friend of mine is one of Steve's semi-pro riders, and he is on the new design. The bike shown in the photo belongs to Rick, another local rider. The guys on the new design seem to like it better than the old one. Steve's bikes are what they are, affordable alternatives to pricier dh bikes. He wanted to build a bike that more kids could afford and thus be able to get into the sport. I don't think anyone would call then innovative, but they get the job done.
IMO thats much better than trying to use steel to make a really light frame, use it just like you said, to get more people into the sport, people that would otherwise be riding clapped out rigs or unsuitable frames.
