I've had one out and most people think it is the most comfortable saddle they have ever been in. The big back pad distributes pressure and supports the back.
The biggest complaint is with connection points, there are no dog snaps for people to put a saw on, just sewn loops. It was too different fo anyone I allowed to use for a few weeks to want to drop $300/US on.
I liked it, but I've been in the Masterr so long I'm used to having those 6 sewn attatchments in the front. Having my flipline on the D ring caused it to foul with the bridge. I could not get used to it.
IMO the aluminum connector is over thought out, it coluld easily be a carabiner.
I think after a little more work and industry imput it will be a very good saddle.
