First of all great avatar

Rottweilers are my favorite breed and dont deserve the bad rep they have at all.Today is my dog Bruno(My avatar) 5th b-day. He weighs in at 135lbs and he really is the most awesome,intelligent,loyal,lovable yet still protective dog I ever owned. That is your dog right?
Back to the topic - I have also seen the videos.They DEFINITELY let you know how volatile they can possibly be but for that to happen is a rare occurence for the most part which you unfortuneately experienced 1st hand.Glad you didnt get hurt and Im sure if it happened to me I would never use them in my PV anymore as well.
As it stands now however I'm willing to take the risk in using them until a protected or even better LifePo4 CR2 with longer battery life becomes available and will definitely switch ASAP from when that time comes.
I have learned how to charge and use unprotected Cr2 safely and properly so my chance of something happening like that is much less than someone that is careless or even ignorant of the fact that there is a safety issue with them. The link on the Alt Smoke site for the Battery University or whatever its called is something everone using these types of lithium rechargable batteries should read.
Now I'll go knock on wood now
