I'm an arborist by trade, I [tree] climb in a Petzl Sequoia SRT and having a rope bridge has spoiled me so much I no longer enjoy time I spend in my sport harness (a BD momentum DS), sure it's comfy still but the range of motion is severely limited compared to the Sequoia SRT.
I've searched and searched but can not come up with one single example of a recreation (rock climbing) harness with a rope bridge as the ventral attachment point. Does anyone know of ANY?
I've been debating asking around to my industry contacts to try and find a retired Sequoia and modifying it (removing all the tree care specific hardware that's just dead weight in sport climbing) but the price tag of a new one is to cost prohibitive for an activity I might get to partake in a few times a month... Hints the endless search here.
Also an arborist here. I’m not sure I would like a bridge on my harness, I’m curious how your motion is limited without a bridge on the rock?
Don’t know of any rock harness w/bridge by any company. I think for a couple reasons
1.) It puts your rope almost out of reach to grab and make a clip on lead, and definitely to boink on a sport route. It would be right in the middle of your field of view on top rope. I just replaced my bridge and made it a little shorter than it came from the factory so I can reach it easier on limbwalks.
2.) There is no advantage to a bridge in rock climbing. I started tree climing in an anchient new tribe saddle with no bridge, tension traversing on limbwalks was akward and difficult. Been in a treemotion for a while now with a swivel, and I agree with you, those positions are more comfortable and I have greater range of motion. In rock climbing, we aren't weighting the rope the whole time like in arboriculture, and a bridge looses its value and becomes, as I see it, further clutter on the harness. When doing spar work, I offen wish I had an adjustable bridge, I’m mostly on my laynard as there is slack in the bridge. I think being on the spar most closely replicates the position of rock climbing in the tree, and my bridge isn’t doing much for me there.
3.) It could be less likely to hold you in an upside-down lead fall. This is pure conjecture, but it seems to me that the bridge redirects force away from the center front of the harness, potentially allowing slack across the waist belt. Except for the lower d’s on the treemotion, I don’t know of any other saddle/bridge that engages the leg loops equally with the waistbelt like a modern rock climbing harness, and I don’t think it would be a comfortable or safe way to catch a lead fall, even upright.
I do think though, that some company should look into modern SRT devices as a rope soloing device. Something like a rope wrench or bulldog bone that is both an ascent/descent device that doesn’t require switching devices to get back down.
