The SG sounds interesting. I was planning on reposting the pics from the ad in which I bought the board. However, there is a big gap of posts that are missing. I will need to take photos tonight. I do not know the actual specs of the Madd, I will try and look them up. I think you are in the perfect weight range. I am 200 with no gear (got to lose a few) and the board perform great on the flatter runs. It was the steeps where I would over power. The Madd was a blast to ride, very quick and nimble. I am just looking for something I can throw a little more hip into.
Where is the SG posted. A quick search revealed nothing.
