For the budget conscious, the Voile split kit is the shit. I split an APO Axel Pauporte 67 several years ago and it works well. I think you have to order the Tractor skins seperately and they are not cheap, but worth the asking price. I sealed up the inside edges with blue laquer that matched the topsheet color perfectly.
At the time a split board from Voile and Burton (only ones available at the time) were way out of my price range.
You did a nice job cutting the board cifex, I have more of a gap in the nose of my board due to a shonky cut, but it has not caused any problems... enjoy.
