I've been climbing with a ness for about 3 years and have been very happy with the saddle for the most part. It is comfy, but that delta just kind of bugs me. Like Tom said about the D in front below the delta, it does lower your COG and makes me feel a bit unstable, but no way are you going to slip out of the saddle. The delta link gets kind of tight when I have my climbing line and lanyard both on the center (4 biners). If I were to get another Ness I think I'd go with the smoke jumper, looks like a great design. My ness has the older style leg pads, Which are not bad, but I bet the newer pads that come around the inside of the thigh are much better.
I've got a Glide on my christmas list --hope I've been a good boy. Until the Glide came out I was determined to get a butterfly, but I really like the looks of the Glide.
-still a ness fan, just ready to try somthing new.
