sound

So Im gonna start this thread for my own education as well. The broadhead thread is great. Ive seen all kinds of "silencers" on the market and would like to hear some ins and out reviews on these from you guys. My bow came set up but let me know some stuff guys...

Came across some pretty cool vids from the SpyPoint Pro-X on youtube the cam has sound, so it makes for some pretty cool shots. Yote flushes a flock of turks... Lots o clucking. lol http://www.youtube.com/watch?v=_Yl5QJ5FbMU&feature=player_profilepage

Early both mornings this past weekend, I heard a strange sound. The best way I could describe it would be an impact driver, the kind used to remove yer lug nuts. It was damn loud and too early to be someone working on something. Any ideas?

Seems random, but whats everyone favorite sound? I aquired a new favorite sound this passed weekend. When a tom fans out and drums, phew, gives me a rush. So whats everyone elses?
