I never worry about a shank hole, just drill a pilot hole and countersink for the screw head, and I am good. IMHO, a shank hole is not needed, the difference is so slight it doesn't matter. The screw will pull the shank right on thru, and maybe hold better because of the snuggle effect. (I like snuggle effect)
My father was my inspiration for woodworking, wish he was still around for more advice. Luv ya Dad.
