Larry...Nice work enjoyed it, sounds really good on the S910......I concur with Scott on the headset Mic..
I personally don't like or use them for myself.

Another thing I notices is the shaky One Brace X stand that would drive me nuts....i would recommend a "double brace" heavy duty one eg: http://www.sweetwater.com/store/detail/IQ3000/

Thanx for sharing your work.
