My favourite whistle right now is the Clarke shiny metal D Shaw lookalike bought from Hobgoblin's stall at the Fylde back in September. I keep trying more expensive whistles but (as yet) I've not heard anything that justifies the price. A life-long lover of the Clarke C, it took me a while to appreciate the new-fangled genius of the Clarke D, but it really cracks on those harmolodic / harmonic partials. Hear it on Teanlowe Fire Dance recorded yesterday & just this minute uploaded on my Myspace page:
