Thanks. Cant do it unfortunately since the sheets don't line up with the studs enough without moving all the studs or getting extra sheets(they've gone from$10 to $25 a sheet now!). So I figured this would drive me insane with the amount of measuring and cutting I'll be doing. Although it should look good when done.
Poor mans 'tile':

They'll be 1.5", 3/4"x1.5", and 3/4"x3/4" randomly placed when done.
Just about have my coping adjustments done now so started cleaning it up and reclearing it.


Then its on to fitting drilling and counter sinking all the screw holes, paint the bottom, screw it all down clear it, paint the decks and support studs and finally skate.
