I LOVE my adjustable setup.
It does not cause any extra clutter... but it does leave my dog bones (actually loops) extra slack to flap around. Because of that i have put a plastic clip on the end of my bungee to secure them
Benefits:
i can lower myself (and hike harder) when there is good wind.
I can raise myself in lighter air when (I can save myself from being t-baged in a lull)
I can raise myself when a big wave is coming at me..
I can adjust the slack so I can sit on the tramp (at almost any part of the tramp) attached prior to getting on the wire and tighten the slack to ensure I don’t disconnect while getting out on the wire.
I built my own system and will try to find a picture of it
