correct me if I'm wrong, but I think even a 1.5mm wall but 20mm diam would be better than the 16mm as wider pipes tend to be more stiff.
I've got a sample 16mm, so will test.
I wonder why most professional scopes like planewave, officina stellare and other RC's use woven tubes.
I've seen some ATM builds with roll wrapped tubes that are actually bad at axial loads.

you nailed the issue there mate.
ATM Roll Wrapped! This is why im hesitant to construct my own CF tube as the CF actually reinforces the epoxy resin. get the mixture right and its pretty damn good. get it wrong they are woeful... your basically using a Resin tube.
Planewave and the like use Woven tubes for one reason.... they look damn good, couple that with extruded rods
they are just grey/black
I would say a 16mm rod depending on your length between cages is possibly a bit to thin. Ide be looking more like 20mm x 2mm as you cannot get protruded rod then woven rod will be fine.
