SPECTRIC makes a very good point when he says: "If the edges are OK ..."
Unless I specifically need every square inch of an 8 x 4 (2440 x 1220), I deliberately seek out sheets with less than perfect edges and then negotiate a good discount (if you don't ask you don't get !). That said, I do remain fussy about the quality of the face veneers. It's then time to get going with the track saw guide rail to produce one good reference long edge (from which all subsequent rips are made). As mentioned by many others, I then establish the first cross-cut reference edge using a bit of good old-fashioned 3, 4, 5 (or 5, 12, 13) or a big framing square before proceeding with all the cross-cuts ...
