TradBox I did go through a Burke romance at one point.
Injuries had ended my fluteplaying days and I wanted to find the best Low D Whistle I could. I got a Burke Pro Viper and I loved it. The voicing was butter-smooth throughout the range and it had an impressively powerful Bottom D that you could honk like a flute.
A friend warned me “watch out or you’ll soon end up with a pile of them things” and he was right- I got several Burkes from Low D to High D, all gleaming in my whistle roll.
What’s amazing is how consistently they play throughout all the different sizes, making it ideal for a musician at a gig who needs to quickly switch from key to key.
Later, after acquiring and playing Low Whistles from a large number of different makers, I realised that Burkes had bores a bit too big, making for slightly harsh stiff high notes. Also the big bores and wide windways made for the least air-efficient whistles of any I tried. As far as ergonomics went the fat tube of the Burke Low D was tiring in my hands.
All of these led me to the more standard style of Low D’s by Goldie, Lofgren, Reviol, MK, etc.
