Do any of you know of long focus (F15 or higher), large aperture refractors with trusses instead of a tube to save weight?

How about tubes made of balsa- would that work, or just asking for trouble? Thanks.

I have a 4.5" f/16 Schupmann refractor and the OTA is made from 1/8" Luan plywood. The tube breaks into two pieces for easy transporting.
