There's now 3 separate incidents that I see where a Jag has blown; two on this thread and one
here. I hope that this is the end of it, not the beginning.
Better contact FIRST. You could ask on the Q&A, or e-mail them (unless someone else has a better suggestion).
Meanwhile, it's probably best to go back to basics if you can--use Victor 884s. They've been proven. Too bad there's not more of them in the kit this year.
