Maybe a stupid question, but why don't saddle hunters use dynamic ropes?

The % stretch makes an actual difference in the types of falls that rock climbers take: 20+ feet. If we take a 2’ fall, the amount of stretch that actually happens is probably not enough to prevent injury.
The reason most saddle hunters and arborist for that matter do not use dynamic rope is two fold in my opinion. First and most obviously is that dynamic rope needs to be longer, so that it has more rope to allow stretching to absorb fall forces. While using dynamic rope on a tether with around 18” of stretch ability would certainly reduce forces, it wouldn’t be as dramatic as if you had 20’ of lead climbing line to stretch. It also stretches some just from putting your body weight into it which feels uneasy sometimes especially when you stand up and turn for a shot.Maybe a stupid question, but why don't saddle hunters use dynamic ropes?
The second reason is that dynamic ropes are not nearly as abrasion resistant as static or low elongation ropes are. When using a rope around a rough bark tree, dynamic tethers show wear within a few uses and would require being replaced more often than static ropes with more abrasive kermantle covers.
The slyde does have impact reducing qualities similar to knots. It uses tight bend friction to slow the fall and lessen impact but only in certain configurations and doesn’t work as well if wet or in snow. Furthermore the configuration shown by kong would be you tie into the slyde instead of a prusik knot with some slack behind it and then a figure 8 at the end of the rope as a secondary tie in. Basically it would replace your prusik. Interestingly though per Kong’s website it is not considered fall protection and does not test or meet the requirements of EN958 for fall protection so personally I wouldn’t consider it the best of anything unless I was using it with dynamic rope.Is the Slyde used for dissipation? I thought it was used as an ascender.
I use 11mm line, so I'm not sure what's up with your Canyon-IV. You are correct that the last hole on the Kong KISA is smaller. All of the other holes are big enough for 11mm ropes. I assume you have to thread 9mm rope through the last small hole to create enough friction to stop a fall, otherwise you'd slide all the way to the stopper knot. My 11mm Predator is actually 11.4mm, so it's a tight squeeze through the holes. I use friction tape to really squeeze the end so it fits through. You might be able to do the same with your Canyon-IV to get it through the last hole.I have a Koog KISA and would like to use it, but I'm having a hard time getting my 9 mm rope (Canyon-IV) to thread through the last hole. The last hole appears to be slightly smaller, but it could be my imagination. The device recommends three loops with the rope for 9 mm but I can only get two. I may need to cut the end and re-seal it after passing it through.
I used tape to get it through. Thanks. To keep it simpler, I may just use a separate tether/KISA for climbing and go with the rappel rope when I'm done.
