Where did you see an $800.00 tag on a SB? They are $680.00 here and I know they are being sold for less in other areas.

Thanks for all the input. The question is, is the xt better than the original? It is shorter but has a bigger brace hight. The Sb is on sale for 600 or the SB Xt is 700? Is the Xt worth the extra?

i don't know this for sure, but i'd imagine the extra brace height trade off is its slower, and they aren't that fast to begin with, so get the $600 one.
