Hmmm, I wonder how I missed this thread. I have used several of the Motorola Talkabout series FRS/GMRS radios with assorted mics while playing Airsoft. PTT is about the only way to go, since most of the boom mics will pic up heavy breathing unless you turn the sensitivity way down, then you need to talk loud to get it to pick up. Kind of useless in a tactical situation, and I can only imagine what the noise of a Multifuel would do to one. Throat mics are nice, but they can get really uncomfortable after you have it on for a long time, and when you get sweaty. Also, (no offense) if you are "large boned" and have a larger than average neck, it can be hard to get it to pick up correctly. Boom mics can be a pain sometimes, and the best advice I can give you is not to buy a cheap one. The Motorola ones are ok, but they can get a little uncomfortable after a while. High priced ones tend to be more comfortable and better quality all around. Naturally this can all change depending on how your ears are shaped, but if you get one that doesn't fit well, or clamps your ear in a vice, you will regret it after about an hour. I finally mounted mine on the inside of my Kevlar PASGT helmet. Some of the boom mics out there have the PTT switch on a little strap that attaches to your finger so the button is always ready to push. One radios, GMRS have better reception and quality, but they do require you to have a GMRS license from the FCC to operate the radio. The license is just a paperwork deal, and doesn't require a test like a HAM license. A lot of the guys have been going to the Garmin RINO radios. They have a nice GPS feature, and can actually let you transmit your location to another compatible radio.
