What I got from the Tomasello tapes and my time with Martin Green is that as long as the pivot keeps transporting the power package, there will be no throwaway. If your hands are moving forward faster than the right wrist is flattening, you will have good impact alignments.
Martin Green is also of the opinion that lag and a bent right wrist is an illusiion. He says that pushing on the clubhead increases it's 'weight' and this increased weight causes the shaft to lag back as well as the wrists. What truth there is to this, I don't know, but that is what he says.
