Which side will you have facing forward, I was thinking with the top facing forward it may tend to ride up over bumps, but with the bottom facing forward it may cut better?
Just a thought, never tried it my self, was thinking of cutting a pc off a 20 footer I have but was going to make it maybe 6-8 feet long for grooming trails. At 16 ft if it works it'll leave a nice finish in a short time.
Good luck
