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...
Been regularly climbing on the Petzl Spin ever since seeing Dan Holiday explain it on climbing arborist and it has encouraged some creative adaptations I'd like to share.
I equally love climbing SRT and DdRT. I can't decide between them, so use both. I can't be bothered to isolate my TIP so...
you can expand your options by using a very long lanyard, like 25'+ and with a prusik. gives you an always available mini ddrt system. you can daisy chain it compact unwinding from the middle. you can attach to the hip, lower d, bridge, whatever, mix it up depending on the situation. If you use...
I was unable to find that friction coefficient info for wood/steel/aluminum in either of your mentioned papers. Like Dan says, real world experience with natural crotching contradicts that.
Considering that harder/denser materials have lower friction coefficient numbers and surface texture is...
here's an elegant variation of the Draggin Tail but abandoning the bight and using a quick munter hitch in place of the prusik&pulley

I used the previous gen, orange&black version. great harness, easily adjustable. big leg straps are comfortable. durable. accessory loops are placed conveniently and easy to reach. Only negative issue I had with it was some bruising initially on the front of my pelvis (asis) from the D rings...
