If I was on spikes often climbing up and (especially) down a trunk, I would be all over an adjustable bridge!

I mean the whole lower d assembly. It looks like most modern saddles have the same lower d attachment webbing.

Good point. If you can see it, it's real.
in augsburg they showed a droptest with the kinisi adjustable bridge and the cam took a couple of bites out of the bridge until it broke the cover. they said it was‘nt a prblem since the dyneema core was strong enough. i wonder if the length is needed to absorb the impact and if a shorter bridge might snap earlier.

I believe these bridge materials (arb systems in fact) are very static and not really designed to deal with or "absorb" fall impact, no matter length. A long long time ago I posted on TreeBuzz a link to a video on arrest testing by ACMG on cams or prussiks and effect on (dynamic) rope covers (biting into the cover/ glazing the cover). To me this Augsburg demo further strengthens reason for ANSI no falls aspect of tree gear/ tree climbing. Tree gear isn't designed to take any kind of big whipper a la alpine/ sport climbing environment. Work positioning v.s. fall arrest. Goodbye back - big ouch.
I agree and disagree at the same time, only because from everything I’ve seen (which isn’t really everything), the hole layout of the DMM and TM are unique. All others I have seen use a rigging plate that puts the bridge holes in a position that pull the plates in an odd way when loaded.
The DMM design is the only one I know that aligns properly when loaded, and I think that’s why their lower Ds are not available in the aftermarket or as replacement parts…they are so good that it’s as if the rest of the saddle was designed around them.
I may be alone in this, and that’s fine, but I might use my hip Ds once or twice a year. My lanyard lives in my lower Ds for everything, including spar work. When I first got a TM, I finally found out what I had been missing, and it was all about those lower Ds. Always in suspension and gobs more room to work above my positioning lanyard on a spar.

I agree with this. The TA 3.2 is the only other saddle that is in this category too (and the pro). I near exclusively use my lower D's as well.
I personally do not like to have my lanyard/flip-line on the lower dees when spurring/rolling up a big stick as it put the COG way too low for my liking. Other than that I’m all for it.
I'm the same. Hip D's for straight up downs, lower D's for pruning and work positioning

I hadn't specifically paid attention to the effect of that change of COG. I'll have to give the side D's another chance, as we have some reasonably large sticks in these parts

On removals I'm switching back and forth from the hip D's to the lower D's, depending on the situation. Hip D's are way better on a spar and for fliplining up. Awkward positions I definitely prefer the lower's.
For trimming it's the lower D's for sure, with a swivel.

For me having a smooth, fluid, and powerful stride is all in the hands. Having my lanyard attachment points down below my crotch and out front (lower dees) just fucks with my flow.

Even if the bridge had some stretch it wouldn’t be much with so little rope in that system.

I find that I rarely ever use the lower Dee’s
I’m more inclined for work positioning to take the lanyard off the hip dee and just hook it to my bridge as a second system.
Granted I don’t wear spurs too often.

I like the side D's too. I prefer the weight distribution shifting from sides to bridge. I feel like lower D's keep the weight in the same place. I've tried lower D's after reading how much people like them, just never felt right. Old dog new tricks, and all...
It might be my frame, longer leg to torso ratio or something???…but I can also imagine that spurring up really large diameter trees would also feel good to be in the hips, especially with all the slack needed between the hands and Ds. Never mind the pressure of a lanyard on a thinner stem vs. a thicker one. Thinner stem in hip Ds squeezes you. Thicker stem in hip Ds relieves pressure.
I’ve run up a few White Pines out here that gave me a taste of some West Coast life, but nothing like the size and frequency you see. For my day to day here on the Beast Coast, it’s lower Ds all the way.

It's not like I've never used the side Ds. When I first started climbing, I didn't realize that you don't climb in a fall arrest harness, but that already had the Ds more forward, and when I finally realized that I needed to buy my first proper climbing saddle, I saw that all the fancy looking ones had very prominent lower Ds and and the bridge was clearly the primary connection, so it just made sense in my mind that the side Ds were generally just for side restraint in work positioning.
When I first got my spurs, I was so accustomed to having my lanyard on the lower Ds, it's just where I hooked it up from the start, and when I did start to wonder why guys were using the side Ds on modern harnesses, I tried it really briefly and thought it must be old habits/ingrained muscle memory and wrote it off. The old schoolers tried to show me the way they did it with a knot directly on the side D, but it was 98⁰ by 9:30 am, and I was just trying to get through this chubby codom incense cedar with a dead top, so I couldn't really focus on the differences, but it worked fine. That was the first time I got heat exhaustion, but telling the story, I remember thinking before I passed out that I should try that side D for spurring again.

You have nailed it with your description of the pros and cons of these 2 setups.
