I have been involved in the SH and sleddog-community in most of these years, allthough not allways in active racing. 
My main concern in breeding is workability, but to be typical siberians, health, temperament, anathomy and breedtype have to be important too. An ideal SH is an easy keeper, friendly, pretty, healthy, relativly fast  sleddog that still resembles his origin from a harsh arctic environment.  Nay-La-Chee dogs are found in raceteams, couches and showrings, most are recreational sledding/ skijoring dogs in active families. I race in middledistance and do show to some extent, mostly in specialties.  All and all enjoying  the life with dogs!
