That's exactly right.
These devices, though improved over earlier versions, evn though they'll do static doubled, dynamic doubled
and single rope technique, they're still not
hands-free devices.
You can make them hands-free, but our requirements say that the device needs to have the soft/hard lock ability intrinsic in the device.
I would bet that ten of us would find ten completely different, though effective, means of attaining lockoff. But we don't really want improvisation here. We want the device to posess it's own ability to drop into a second stage of friction that DOES make it, at that point, a hands-free device.
Other requirements were that you should be able to soft or hard lock one-handed, either going in or coming out of lockoff, and be able to adjust your position while in soft lock, also one-handed. In a perfect device world, you should be able to work the crown and tend slack while in soft lock. You wpouldn't necessarily have to live in soft lock while up in the tree as going in and coming out, as mentioned, should be one-handed and take about one second, either way, since in and out of soft lock is nearly as common as slack tending.
So any ideas on how to create an intrinsic soft-lock in these devices? This might be a great time for a digital design. Describe it, and I will 'build' it.
