Tie in point isolation alternatve

just a quick Idea that I had, If I connected an ascender like the basic to a webbing loop on my harness and used it to move over anything caught in between the ropes by attaching the basic above the branch blocking you from advancing to your tie in point. Then unclip your split tail and advance with the basic past the branch then advance the split tail above and clip in then advance normally with your split tail.
This could save everyone the trouble of dealing with isolating your tie in point

Cool idea. I use a Tibloc on a sling/tether to deal with a similar situation SRT climbing (moving the rope through a redirect so I don't have to climb through the redirect). If I run into a limb captured by a DRT system I usually just lanyard in, unclip the carabiner on the standing end and move that up and back over the limb, then clip it back in to my harness. For most broadleaf trees isolation is not much of a problem, for conifers it can be a big problem, which is why many folks prefer to access conifers SRT, no isolation required.
