Edit: Added headings to enhance readability
Intro
Bear with me, guys. I've read allot of stuff here over the past few months, but very little of it makes sense or 'sticks' until I get out and climb and experience the situations which highlight the strengths and advantages of various devices or techniques I've only read about. I'm learning...
Using Lanyard to advance, but no need for 3:1 on ascent
Upon considering this further, I think the most efficient thing to do, since the hitch only needs help on descent, is to toss the lanyard up and cinch it, then ascend SRS (1:1) to it. Once I am up to the choke and want to descend - or anywhere along the way - I can lanyard in, convert to a 3:1, leaving the cinch in place, descend on just my hitch, then remove the 3:1 and retrieve once I'm back down to starting point.
Upside to using 3:1 (or, rather, non-downside)
I also just realized that this wouldn't require any more rope than MRS would, and possibly a little less, since the three parallel legs don't extend from my starting point all the way up to the cinch; it just extends a few feet ahead (the distance is determined by how far I can advance the hitch/ascender holding the pulley - arm length, more or less).
Climb Line instead of Lanyard
I'm also starting to wonder if there is a way I could accomplish all of this with just the climb line while using a base anchor, by 1) converting it to a choked anchor when I reach the PSP (to hold the basal leg in place once I pull slack into the working end), 2) pull slack though my multiscender, 3) toss a bight with multiscender up as high as I can get it across a branch (and hope it comes back down to me), 4) clip back in to multiscender with it up across the newly acquired PSP, 5) pull enough tail down to attach foot ascender, and 6) continue on up.
The purpose of the conversion to a basal cinch is simply to keep that side from eating up all the slack I pull in the working side. I'm learning that rope is heavy, especially 85' of Vortex (1/2")!
I apologize if this is all very basic, and there are already a billion threads on it.
Lanyard vs. Climb Line
The reason I was thinking "lanyard lanyard lanyard" at the beginning of the thread was because the weight of the line along with the multiscender seems like it would be prohibitively high to toss upwards, whereas a lanyard would be lighter. If the branch was located 6' up, it also seems like I'm going to have to pull soon the order of 4x that much slack in the working end in order to get a bight up and then back down to me. Perhaps this is where a throw ball and throw line become useful? I could toss that up over the branch and then proceed as if setting a basal anchor from the ground?
Edit: Or, as
@Burrapeg pointed out, maybe I could do all this using the tail. BUT, that would necessitate moving my multiscender. I'd prefer not to do this, as I'm using an HH2, which would be a little bit of a pain to have to untie, move, re-tie, etc., etc. (although, I am getting pretty good.
Check out my understanding of the scheme using the main climbline (i.e., probably just regular ol' advancing. durrr):
