Thats a fairly comprehensive set of keys , and if you want any extras you are going to have to pay a bit more than for Generations !
Tony Dixon does nice Low A , Low G , Low F AND Low D , though the Low D does need a reasonable finger stretch . Check out Tony's web site - They are NOT silly prices , compared to Chieftains and Overtons , and are better than the Susatos in my opinion ! Failing that , get your daughter the new Dixon High D - Aluminium body , PVC mouthpiece - A lovely whistle to play , and a LOT nicer than a Generation , though a Generation that DOES work is a Good Whistle .
