If you're not 100% set on the Arbor, like another poster said you can use regular bindings on an EST board (i.e. get a Custom X and burton non-est bindings with an EST baseplate). I sort of wish I had done that with my T7 and C60's because I'd love to mount these bindings on an exotic, stiff, big mountain stick (Kessler or similar).
edit: According to Arbor's size chart, you're right in the middle of the ideal range for the 166, so I'd be tempted to go for that, especially if you're using it for hard carving and powder.
