Thanks for all the replies.
I've ordered the hub and once I have that here, I'll do some measurements and order spokes and nipples.
I guess I can 'unbuild' the wheel(s) while I'm waiting.
Any recommendatins for a spoke supplier? (I'm in Canada so shipping can be an issue but a spoke supplier local to me is charging twice to three times the US prices I've seen...so I'm wide open to alternatives.)
