VTclimber--the Smokejumper is the only Ness (New Tribe) saddle offered by Sherrill. It's a good saddle. There are benefits of going through New Tribe direct: 1) you can order different sizes of waist belt and leg straps. This could be especially advantageous for women, where smaller waist to leg proportions may be more common. 2) you can specify many options in construction, i.e. gear loops, equipment rings, gear bags, D ring size.
(Burnham's two cents worth: do not order the brass boat snap style gear hangers...they are murder for hanging up in small limbs. And do order the large D rings...better for those times when you want to double lanyard, and just easier to clip in to.)
Outonalimb--the saddles you see on the New Tribe website or in their catalog are designed by Tom Ness, co-founder of the New Tribe company. Thus, they get called Ness saddles by some of us. They just aren't identified that way by New Tribe. Note that there are three basic variations, and as I said above, many optional features. I personnaly use a customized Work Saddle.
It is interesting that New Tribe does not appear to sell the Smokejumper version direct...I have only seen that offered through Sherrill, which is, of course, a great company to deal with as we all know. As I said, the Smokejumper is a good product.
