Looks like BD scrapped the N-force design.

I was wondering if they were pushing out a new model since the n-forces have been on such steep clearance.

Anybody tried these?

Not sure if anyone else had the same issue with the n-force models, but the handles were uncomfortable. They seemed to be designed to be ergonomic, but the hinge created a sharp bend that hurt if you grabbed on or near it when jugging.

Don't fix it if it ain't broken. It seems like the new design is similar to the Petzl model at least in overall shape.
