I just picked up a Bosken NS tenor neck off e-bay. I'll be sending Stephan an e-mail on the neck type but does anyone have the model definition of his necks? This one is a NS 68H. Not sure if this is the thin-wall model or not. The model 68 neck on Roberto's Winds is described as free blowing, powerful low register, full of overtones. That is a similar description as the model 66 also.
