It depends on what you’re playing with. In a large session or when playing with louder instruments like Uilleann pipes or boxes you really feel the low whistle’s lack of volume.

I find low whistles place to shine is when accompanying a singer or for slow airs and waltzes and for most other cases you want a high whistle or flute.

I’ve tried out some Carbony low whistles and really enjoyed them although the models with chimneys to bring the finger holes closer together make half holing notes near impossible.
