I guess you and I will have to disagree.  If so, the data I read from Gougeon Brothers is a lie.  I have tested it in my own shop.  I do laminate.  Laminates are more flexible. I am familiar with Simitar props and the twisting. In fact, Wittman used that to his advantage.

The aerobatic planes Jon Staudacher built had cantilever wings.  Like many small planes the tail surfaces were rod-in-tension braced.

I stated, 'Lamination will NOT increase stifness by itself.' I stand by that. In thin laminations the glue itself can lock the fibers and cause things to get more rigid.  I mentioned other things that casue lamiantions to be more acceptable. Wooden structures are quite complex.  I do not believe I will ever fully understand them.

I have seen a few interesting things in mixing Glass-strand or Carbon-fibre in epoxy and wood - and other substrates. There has been very litle published on fatigue of mixed composits (wood/modern-stuff).  

Wood and laminated wood are the superior materials for fatigue resistance. As a structual material, it is difficult to beat.
