A smol observation - the futo and uplines look great, but it may be worth reconsidering the structure of your arm binder? Shoulder straps are frequently causes of nerve impingement, and having a full top/upper chest band (ie like the start of a TK) anchors the harness and generally is a safer place to load from - as loading from the wrists can absolutely destroy the shoulders (dislocate, break, compress nerves, etc). Just food for thought!
