Sooooo, I know this is a nice ez question with a simple answer. Wood or Nylon prop- what are the advantages of each, disadvantages, etc. And on an entirely different note, is there any prep work that should be done to nylon props? I just got a couple of m-a props, and they have some really sharp edges, and a lot of moulding flash. Should I smooth 'em off, or just leave 'em be?

TIA,
Andy
