I get the feeling the hypersonic is one of the great boards of all time, or at least one of the most influential... I should buy it and stick it in a frame behind glass and hang it on my wall for future worshipping. The fact some people hate it just makes it more brilliant if you ask me. It took alot of balls for SB to make such a radical design for its time.
Thanks PG for pointing out the downside of this board for me, but at $250 (ie virtually free) those reasons are not enough to cancel out what Mark H is saying.
But yes PG, i will look out for a board like you suggest if I can get one this cheap. For real strong wind I currently use an old 80 litre wave board. It weighs nothing, I love it!
