My O’Riordan B Flat…hands down…NO other SOUND like it. Absolutely
the finest B Flat I have ever played. If you have never heard one, find
someone who owns one and give this magical whistle a listen… It will be
worth your effort.

But I think I’d probably like a Reyburn, too.
I have a maybe-15-year-old Generation Bb that is kinda OK with tweaks. But Gens came up so much in this thread that I think I’ll pick up another. Who knows, maybe I killed it! 
Interresting ! I have a generation Bb that I enjoy a lot. Where did you buy the hoover Whitecap ?
How would you describe the character of the hybrid whistle compared to the generation One ?
