What's Your Favourite Back and Sides Wood?

I've placed a poll in the sidebar that allows you to vote for your favourite back and sides wood species. I think I've covered the usual suspects, but I'm sure I've omitted some other popular choices! If you voted "Other", perhaps you'd be good enough to add a comment to this post to let everyone know what it is. I'd also welcome your comments as to what particular characteristics you feel your favourite species offers.

Cheers
Pete
