I know that alternating wood grain when gluing up solid wood to make a tabletop is woodworking lore, but if i fasten the boards together with pocket-hole screws and then attached the top with figure 8 fasteners do you saw-dusts fiends think it will still cup? Two of the boards are not very goodlooking, just trying to satisfy a client…

Boards will cup when moisture is released unevenly from the top and bottom. Pocket-hole screws won’t matter, but does make the assembly a bit easier. The figure 8 fasteners will help to keep the top flat (by brute force) and still allow for the top to expand and contract.

Finish both sides of the top, and this will help equalize the woods natural movement from top to bottom.

Not sure what you mean by the boards not being good looking, but the boards you use for a table top should have the same moisture content. You should use a moisture meter to be sure. The material should be well acclimated to your shop.
