Funny, 6 months ago, it was unheard of to have any kind of issues with LiPos. Now that they are becoming more main stream a lot more "issues" are coming to lite.
I never said that one over the other is a better fire, but if you want to follow the guidelines that ROAR put out, the cost of a "D" class extinguisher is a lot more than we expected. Now check your home, or the gym you race at for a fire extinguisher, I bet, most, if not all are only "A,B,C" which will be pretty useless in a Lipo fire, and in some cases will just add to the problem.
