Thanks everyone for your responses.

Alsion: Do you have a tuneable or non-tuneable Tony Dixon High D ?

Sarah: you have a different opining from Kaleea and Willa on the tuneable High D Susato - who is right ? Also what wooden whistle would you recommend as I am interested in getting one - what keys are best for English and French tunes ?

My quandry now is do I buy a tuneable High D Susato or a Tony Dixon one ?

Can someone sway me or do I have to buy both ?
