I've just been looking at the Kreg Deck jig being advertised on Lee Valley's website.

was wondering about fastening deck boards as demonstrated by this jig. For those of you experienced with building decks, would the screws need to be inserted on both sides of a deck board, (assuming there's just enough room for screws to be inserted on a 45 degree angle both edges) or just on one edge? And if it is just one edge for fastening down a deck board, wouldn't there be a tendency for the opposite unfastened edge to rise or perhaps cup over time?Thanks
