Chieftain V3 and MK Pro Whistle - Comparison

I’ve got an MK Pro and a Chieftain V3. I play them side by side so that you can hopefully get a bit of a feel for the differences between the two. The MK does not like the last hole covered, which causes problems at times. I’m trying to find a better way to do things. I make an attempt at “The Butterfly“, “Gallagher’s Frolics“, and a tune that may be called “Ginny“ that was played by Eoin Duignan on the album “Coumineol“. I’ll get it one of these days. Other things to work on: Breathing and Facial expressions when I goof up. :)
