    Petzl Midline Zigzag

    The Shift has 8 points of contact, whereas the Reflex has 7. I think also, on the Reflex the bottom most contact point puts a rather severe bend in the rope and is likely to wear there quickly, leading to early slippage. My 2 cents.

    Petzl Midline Zigzag

    Here is the thread about the "Pulley/Rack" I was working on in early 2012. I had no knowledge at that time about the zigzag. I continue along this same line with the Lynx to this day.

    New device from ISC

    I expect that they will require the same Wrench above (for SRT) as they do now, but with the ZigZag links below open on each side like the Reflex. Designing a full mechanical is no easy task, especially for SRT midline, so I appreciate ISC for the effort. It would seem that replaceable wear...

    New device from ISC

    Tachyon is, in my experience, one of the best ropes for gripiness in a mechanical device. I still think a compact rope wrench style aid, with short stiff tether could be built into a reflex style device (much like the Blackbird). That being said, has anyone heard rumors of Petzl coming out...

    This 9mm rope with 3/4 inch pitch with the custom sheeves holds just over 300 lbs SRT.

    Wow, very sobering. It seems like only a matter of time before our infrastructure of keeping track of money transactions in the globally connected banking systems will be compromised.

    The first Americans: how "clovis first" is a perfect example of the basic flaws inherent in science

    Apparently this is because of the multiple sedimentary layers laid down by the flood.

    Oregon man who shot at arborists fired hundreds of rounds, police say

    Mental case with paranoia, Thank God he missed. One young man fired a shotgun over our heads, and two angry men have approached me with rifles. The last was an ex probation officer. Drugs and/or isolation will make you crazy.
