I kinda have the spectrum. I keep two saddles fully rigged. My lightweight mesh saddle has RescTech and I use CT Roll-N-Locks instead of kong duck or ropeman. I also have 8 mm rappel rope that I use with a figure 8.
On my solid panel saddle, which is heavier, I use some 9 and 10mm ropes with ropeman 1. Typically it’s canyon elite but it does feels larger that my canyon CIV. I also use thes ropes with the Safeguard.
When I tree stand hunt, I tend to grab the 8mm RescTech. Even though I like the other ropes, the reduced bulk is nice.
I keep telling myself to sell some of this stuff and standardize on one thing. I think if I had to choose, I would lean toward the 8mm RescTech or the 9mm Canyon CIV. I think Canyon CIV is hard to beat for its size, weight, compatibility and price although it is a little stiffer. But I find that useful in our application.
