Have been playing with the 1/2" KM-III some more... it doesn't creep under full weight, even with both adjustments at their loosest settings... 1T/6B... but, it also doesn't really work. It's virtually impossible to break it to descend, even using both hands. When it does go, it's pretty much wide open, with not much control. So, that's not looking real promising. Perhaps the RE version will hog out the sideplates/arms like Jaime was talking about in Update #3 video, but this version still has flat plates, and there just isn't room for the big rope to move with weight on it. That's kind of disappointing, because the added friction of the bigger rope looks like it is more than enough to make this thing work for bears and possibly
@oldoakman, too. I think the sideplate milling is going to be a must-have for it to work with 1/2" ropes. Possibly even some tweaks to the length of the arms and center section, I don't know.
It does creep on some ropes I've tried, until you get the adjustments dialed in. Even the ZigZag creeped on the KM Max rope, so it doesn't surprise me that this thing will, too, on that slick rope. I went one setting tighter on the lower adjustment (I'm now at 2T/3B) and this seems to have stopped it, without adding too much drag. I wanted to play with the 11.7 Yale ropes some more, but I'm tired. It will have to wait until tomorrow night.
A little bummed about the 1/2" rope, but I knew that could be a problem. I'm thinking the 11.5 to 11.7 ropes are going to be the best. I love the KM Max, but it might not work for anyone much over 200... so I'll start playing with the bigger ones. Also, things could change a little once it wears in a bit.
