The truth is that if he can't make a clarke sound good, he'll have less chance with a low DGeez Ed, what a nice way of saying, "Jenny, your husband ain't worth a tinker's damn." (:<))
Actually Jenny, you have gotten the good threads linked above and they should be of help. Happy reading, and if you have additional questions, just ask.
Personally, I think your husband should stop mucking about with the Pennywhistles and move up to the quarter jobs, skipping the Nickelwhistles and Dimewhistles altogether. If you're rolling in green, I'd suggest bypassing the Quarterwhistle to and go right to the Buckandaquarter Whistle.
