Deck Replacement 18 SF

[uncleboo]

I'm just beginning the work to recore my transom, deck, helm pad on the console, gunwale caps and the hatches. Going to do all the demo work myself and have a friend, (professional fiberglass guy), do all the glassing. My question for right now is, is it less expensive to recore the old deck skin or have the new deck fabricated from one of the composite materials? Speaking about the stuff that has 1/4" of glass, lightweight core and a thin coat of glass on the backside. All thoughts are welcome.
