Does anybody know an alternative source for pegs for the planes? On the pegs from the original planes I could bite the thin bit a little, they would flatten and then would stay attached better. But the new ones are a higher grade of plastic and don't deshape so well. Is there an aftermarket peg where the plastic is a little rubberier? I have a bunch of kids playing and they have trouble keeping the pieces together when they move the planes. With one or two kids it's no big deal, but with six or seven in the same scrum it causes a bit of an issue.
