The ply did start to fray on a few occasions and was coaxed back to flat with thinned white glue. Overall, good material choice for some designs. Glad they were able to think outside the box and introduce different materials.

It also allows for some wicked fin designs that defy grain considerations without need for lamination. Tough to create, though; I've cut rings and some fins, sloppily. If only I had a laser cutter!

Gotta agree with you. One of my favourites (okay, probably my #1 all-time fav) is the SSV Scorpion. Fibre/cardstock parts made it possible.

Loved the Centuri Super Series! For those alone I'd have to say they had the best exotics. Would love to see them come back.
