I must say that I have heard Tom's Silkstone and Clarke whistle's and they are beautiful (no doubt in part due to the player himself). They both have very distinct and beautiful sounds. I must add, however, that I have only every purchased a set of Generation Whistles from the Whistle Stop and I love the sound I get from my C,D, and Eb whistles! They may not always be in tune with other "brands" of whistles but for solo playing or playing with other instruments, they are the best buy of whistles (in my humble opinion).
