Awesome guys, thanks for the quick and informative replies. Tried lots of different lanyard combos, favorite right now is a Zillon on Tri-Tech. Super smooth, compact and is rated for life support on SRS. The problem is it tends to bind heavily that way, doubled around a spar or over a union it’s sweet, but singled out it tends to lock. Like loading a traditional English prussik. You can break it, but takes a fair amount of effort. Tried several ropes, basically all the same result. The manuals says to two-hand control feed in that configuration, and that helps, but not really productive, takes too long to free up that second hand 100 times a day. Looks like this is a vast improvement on those shortcomings, as well as additional features like MRS.
I would agree, it’s nearly impossible to find one device that’s works well in every situation, but it looks like
