Dude!I finally had time to play with the Klemheist and had these observations:
3. Flimsy ropes will collapse easier than stiff ropes. I don't recognize the ropes you used. If you don't know the brand and specs of the rope you're on, even if you got it from a saddle supplier, it might not be fit for the application. If the supplier of the rope isn't giving you that information or references to it from the original manufacturer, I wouldn't use the rope or the supplier.
I have soo many different ropes and hitch cords that I honestly can't remember what name brand half of them are!
I have tried dozens of combinations of rope vs cord and another bakers dozen of different hitches. So yea, I kinda know what I like so far and the Klemheist ain't really one of them. Nowadays I only use it on a foot tether as a tether handle and for going around limbs or a pack/bow holder hitch once at height...Maybe this weekend I'll try the Hedden some more?
And really, I only use the Klemheist as a secondary hitch anyways since I've learned quite a few better ones in the last year or so...
That being said, almost everything I use is either rated climbing rope or hitch cord, or accessory cord that is definitely gonna hold my skinny ass up in a tree .
