I just recieved a Kerry Pro Tunable F from Hobgoblin Music. It’s a great whistle and I’m very happy with it. The C natural fingering oxx ooo is the best I’ve heard on any whistle I’ve played, the breath requirements are very low so you can play a long time on one breath. Thanks Phil
Excuse me while I ‘pick some nits’:
OXXOOO, that would be Eb on an F whistle 
All minor details aside, the Kerry Pro low F is a very nice whistle indeed.

Mine’s a KP low G, and it’s my favourite low whistle (my others are Susatos and a Chieftain D). My only problem is the one faced by all the big metal whistles… it does take a while to warm up and get in tune, but when it’s there it’s a beauty.
I have yet to play an Overton and look forward to a chance to compare the two one day. Maybe when the nearest K-Mart gets changed over…
