All plywood is laid in a "crossply" configuration. I didn't think I'd mention it before but as you've brought it up again and are using your own, invented term for it, I thought I'd put you straight.
I make and shoot naturals, not board cuts. But there's nothing wrong with them, in fact most of the current interest in catapults owes a lot to the Multiplex makers.
Who said I was talking about you ....
Fair enough! Lol!!!!!!
You jumped in with both feet then ... Also Just try Google search for Cross ply wood You will see I didn't dream it up ... Now stop making me talk about crossp
