Decks, Patios, Porches and Docks - The building has begun

My contractor has finished the framing and I have started putting the decking on the stringers. With composite material, specifically Correct Deck, it is turning in to a royal pain in the butt. I am using thier correct ty system, which requires me to line up a plank, anchor the end, then pound the plank into the ajoining correct ty and screw in another ty to hold that plank in place. Problem one, the planks are slightly bent, up, down or sideways, so they do not always fit in snuggly. Second problem, for this to work I have to stand on the plank and pound it in, then screw in the ty. All this is done in the bent over position. My back is killing me!!! :mad: Third problem, since they have a bounce factor in them to start with, I can hammer away and it will go in then bounce out, so I have to go forward, screw in a ty then go back and pound in the previous one and reanchor it, then move forward and repeat the process.

So question, does anyone have a good way to shove a board over so that I am not pounding away to no avail in the bent over position? :confused:
Any ideas at this point may save me a trip to the chiropractor.

Lay the composite decking on something truely flat to help eliminate the bowing. I laid all the decking on my framing at a 45 degree angle on the far side of the deck stacked 6 pieces high. Then i worked towards that point from the other corner. As far as the fastening system you are using, i have no clue. I only installed GEODECK 5/4 and 5/4 T&G with tradional nailing of both.
