Hey fellows - three questions:

What diameters did you end up using for each tube?

Where did you source your geometry?

What species of bamboo did you select - there are so many! And what qualities did you base your selection on?

As a complete novice I suppose I will just copy a bike I already have - a GT mountain bike - but any other resources are helpful.

Looks like I will have to buy raw fresh-cut bamboo here in Perth Australia and dry and treat it myself!
