Fact is, though, this is a high-school competition and it's much easier for a high school student to inadvertently damage a plastic tank in a way that will cause a dangerous failure than a metal tank. I wouldn't be so concerned if these were only being used by adult engineers, but they're not. I certainly would rather be safe than save a pound or so of weight.

The failures noted so far this year have still been those 2013-era white plastic tanks to the best of my knowledge. Not the 2014-era black plastic tanks.
