Like I said in the beginning. This topic always ends up being a matter of personal choice. You can come up with all the scary stories anyone can imagine but in the end we all do what we think is best and necessary. If the AMA, IMAA, IMAC aren't concerned enough about it to make it mandatory then just maybe It really isn't necessary to spend that $60.00.

By the way. Has everyone seen the combination smoke pump/optical kill switch offered by RC showcase. Pretty sweet gaget and the price isn't all that bad considering you get a complete smoke pump system with your kill switch. You can get the smoke pump alone or for just 20 buck more you get the kill switch along with the smoke pump. For 20 bucks I might consider using one but that's the only way. Check it out.
