No power tools between the initial gel coat spray and assembly after the boat left the glass shop. No sloppy work to grind off. And our work was not hidden later by interior panels, etc. We took pride in creating a boat where all the fiberglass had its strands pulled straight, the weaves even and natural, the edges straight and rolled down so clean we barely had to hand sand the edges.

CF on bike parts scares me. It is all done inside molds that are closed after layup and human eyes never see that layup again. It would be much easier for me to trust if I didn't know the difference between a worker's good day and his bad days. In my work, it was all open mold, so even on a bad day, I had to do work that my coworkers and bosses could see. But once the fork mold is closed for vacuum bagging and bake, nobody ever sees it. And my life is as much at stake when I ride a near 50 mph descent as those who sailed my work to Hawaii.
Considering the billions of kilometers which have been safely ridden on carbon fibre bicycles you needn’t lose much sleep about CF safety at this point. However, you be you, and if you are more comfortable with legacy materials great. But with your heritage technology there are many risks as well, from rolling a tubular to forged aluminum parts catastrophically failing, both of which have happened to me in the distant past, realize that risk goes beyond perception. Over the years I have had a Teledyne Titan crack at the head tube, Dura-Ace solid forged crank arm fail, Regina freewheel literally explode, Super Record BB axle shear, numerous axles break, spokes break, seatposts seize, dozens of wheels come out of true, etc. the good old days were really not as good as everyone remembers.
