Other than the button noise, any other comments on the 703 mic?

Bob -
The Vaseline on the pivot helped a lot. The noise is still there, but I think
I can live with what's left.
I may try some of Stuart's padding suggestions. The noise is from the button
and not the switch and padding out the pivot point and where the sides of the
button brush the case would do the trick, but there is little clearance in
either spot.
Thanks for the help, Bob and Stuart.
