AGAIN I say ...

The foam offers NOTHING but a form for the fiberglass mat bracing.

...and the same goes for that styrofoam sheet.



, but then thats all it's supposed to offer, the increase/added stiffness is not the foam itself, its the increase in the depth of the cross section ( it could almost even be just air , except that is hard to form)that one is trying achieve. Steel ubing mightwork well and easy, but hard to imagine it outperforms foam lb for lb.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
