Another lightweight solution I tried many years ago on my 12" was to use 4 triangles cut from marine plywood, with 1 layer of fibreglass mat on each side instead of 8 poles.

You will need to make a simple jig to drill holes accurately so they wind up being precise isosceles triangles and interchangeable. With a jigsaw, cut out most of the interior to minimise weight.

In practice it was light and quick and easy to assemble with rather fewer nuts & bolts than traditional trusses. 600 long is peanuts, and will be easily stiff enough.

FWIW il s'appelle 'Serrurier' pas 'Surrier'. Mon dieu, ces anglais !
