I have always found the edges on a new board to be perfect. I usually take a file to the it to detune the tips and tails about 3 inches down the edge. I also have found factory was to be excellent for about the first 5 or 6 days depending on conditions.I've actually ridden factory wax as much as 15 days or more on a new board and found it to be fine. Its all about consistency, as soon as I wax a board I have to get used to the new wax.,... old wax is predictable,, rides just like the day before..
