Stokes Basket rigging/strength of directional 8's
Got a question for ya:
How do YOU clip in to a Stokes as a victim attendant?
Could you tie a Directional 8 with both the main line and the safety, clip the stokes in each knot's loops, and then come down with 4' or so and then clip your harness into both via Fig8 on a bight (& prussik for adjusting) WITHOUT losing much system strength? How much stronger is a full 8 as opposed to a directional?
Why would you use a double line lowering system on a Stokes? Not a Main and a Safety, but two Main lines to lower. Seems to me it'd be hard to maintain the proper angle for the pt.
In unrelated news, why the hell are we still teaching the bowline?
P.S. - I found the knot strength thread further down in Specialized Rescue, per CMC Rope Rescue Manual, a Fig 8 on a bight is 4% stronger than an "Inline 8", which I am assuming is what I know as a Directional 8. Which brings me to another question. If a Fig 8 on a bight decreases strength by 19%, how come a Fig 8 follow-through weakens it 21% (I may have my numbers backwards, but you get the idea) if they are the same knot, just tied differently? Hmmmm....
