What the last two have said is all good advice and can't add much to what they said. I used muzzys for a long time and they were always a good head never had any problems with them. This year the mech bug bit hard and have been shooting the G5 Tekan two's and they are flying great. Give a little more info like they asked and maybe we could get a little more info for ya. The other thing you asked about, sound is a lost cause. You will never get that thing to be quite enough to ever be able to have an advantage with it so my only advice is give up and learn to accept the noise. Alot of people try to quite there CB's and the best advice I have ever heard is a good set of ear plugs! If you are comparing it to your compound you will never even come remotely close to getting it that quite. Anything you do put on may help a little but will also only help slow your CB down at the same time. Make one good shot and it won'yt matter. Also, I am shooting a Horton supermax 175.
