i can obviously appreciate the skill in making things like that and stuff... but i'm not sure i'd want to use one myself. i like using slightly longer than normal patch leads, so i can loop bits of guitar stuff and then send it back through different pedals, and with the longer leads i can hold pedals on my knee and move them around while i'm playing easier. those things look a bit too constricting for my liking but i can understand why they might be perfect for other peoples style of playing
