Relax,funnin a little with you is all.I'm sure if you dig a little you will find your answer.All these beware threads,while I get it,perhaps some new information,perhaps a different opinion kinda get me scratching my head.You have folks using these things for years,nothing,you have a fellow look sideways at one for the first time and he's less a few fingers.You get into this sport,spend enough time,know enough folks,listen to enough stories,stuff like this is going to happen.Gun powder,electric,gasoline and alike,natural gas,LP,fast cars,guns,high places,certain woman,ect.ect.ect play with any of this stuff long enough,even in the best of times s@$t happens.No rhyme or reason sometimes,it's like the gun barrel steel debate.All you can do is try to do everything in the safest possible way and hope your numbers not going to come up.
