great way to explain it! the big benefit of climbing on the petzl spin is the single direction pulley removes friction as you would expect of a pulley, but adds enough friction on the holding/tending and release phases to run it with easy finger pressure so it doesn't destroy your hands and biceps
Absolutely valid so long as you get a secure working position with both hands free. Still I try to prevent shock loading on the toothed-cam ascenders. Some folks will redirect off their hand ascender too. Probably fine in most situations but a violent enough bounce may damage the rope.
good point. Even installing your climb line can damage the cambium in sensitive trees so using a canopy anchor won't prevent it either. But a friction saver does and is remotely retrievable. And you can SRT off a friction saver all day long.
Reminds me of this recent post:

This is not a "system"
These are just a few ways that you can integrate SRT into your DdRT session. It is implied that DdRT is always available within an SRT session or that techniques implemented like the SCAM give mechanical advantage on SRT. Realistically, DdRT is much easier on the body and...
you could use any retrievable redirect you want to. There are many. I like the beasthorn because it requires nothing more than your rope. the tail has no climber weight on it, I just need to keep it with me so I can retrieve the knot remotely.
imagine another option would be to tie the midline knot and pull up two static lines on your floating block. Do the entire climb SRT with the two static lines. Not something I've done.
If you like the knee ascender, just wear it and use it when you switch to SRT off a redirect.
I use a knee ascender regularly too but I don't prefer it. But some trees call for it and I wear the knee ascender the whole time. But sometimes I just need to climb 50' and then I can switch to DdRT. So I put on two foot ascenders, tie a midline knot in my moving rope, and pull up a floating...
sorry man. I didn't maybe give enough context. I like to climb DdRT when I can, but I also do a lot of SRT climbing as well. These are just some ways that you can blend the two. For example, you're climbing around in a tree MRS and decide you'd like to redirect and work a zone SRT. So you anchor...
the friction is about equal to around the horns on the portawrap. you're not going to be doing any heavy rigging on this device. If you get into some heavy rigging scenarios, you'll want to setup something more robust. So considering the weights you'll be rigging off it, you'll not see any...
this technique for a fully retrievable configuration. MRS line from above left. Run the tail of the MRS down to your destination, then terminate it using the "beasthorn srt redirect". When you later pull on the tail, it will release the knot. Now you are on SRT. Setup your next redirect again...
I tie a midline knot and lock it with a carabiner before pulling up the floating block,. that gives two static lines to climb, one for each foot ascender. Place your device on either leg. Once you reach height, untied the midline knot, pull up the working end, and switch to DdRT
You are not comfortable climbing on a floating block. That's ok.
I've done dead hazardous failed removals using floating blocks strung between very tall firs hundreds of feet apart and tightened via grcs. I've installed a floating block on a bucket truck to descend down into tight places. I...
why would you say that?
the stopper knot even goes to the side pushing the triple action side plate in the closed direction.

from my Zillon lanyard. I don't know what brand of rope it is, guessing it was exclusive for Petzl to use in their lanyards. It's quite bulky, maybe 12-13mm 16 strand, nice for the bridge.
The Zillon is butter, but it's sketchy for a lanyard IMO. I didn't care for the surprise releases just...
