Low whistle observations

I own a Howard Low D, a Dixon Polymer Low D, and a Susato Low D. They are all nice instruments in my opinion. The Dixon is the most novice friendly I think and has a nice low whistle sound. The Howard is well made, has a great foggy sound, but is a bit harder to play than the Dixon. The Susato is really nice for the price. It is a bit harder to play than the Dixon and a bit harder than the Howard for me to play. I use the piper’s grip on all three given that I have small hands for a man. My wife and daughter’s hands are the same size as mine. I am 5’8" tall and wife is about 5’1" and daughter about 5’2" or 5’3". I am learning to play the bagpipe practice chanter and has actually help my whistle piper’s grip even though fingers are fairly different. I hope this helps. These darn whistles are not cheap and are hard to find. Seeking advice and research are a very useful thing. Good luck.
