I believe this point will get argued 'till the end of time... along with gun laws, speed limits, why you called in sick for work yesterday and why your wife makes you put the seat down when you want to leave it up. Those who are going to touch their tails are going to touch their tails, those who dont like it are going to continue disliking it as I dislike the fact that my AR15 must remain semi-automatic [&o] . Rather than fight about it lets encourage the fact that if you are going to willingly generate a considerate risk in the name of fun, do it in a way, time or place that puts ONLY YOU at risk... because if I'm going to get a 9000rpm propeller to the head, I'd like thank myself... not you.
