When preparing for a trad climb, I usually divide my rack into separate groups where each group is connected to a single carabiner. So for example all the small nuts go into carabiner 1, middle range cams go to carabiner 2, etc.
The problem is that when I need a specific piece, I need to be able to separate the desired piece from the carabiner. This is often pretty hard to do with one hand. The other pieces can be pretty heavy too.
I was thinking that maybe there is a solution that allows me to detach a single piece and put it back (if it does not fit) easily using one hand. Maybe a magnet of some kind or a detachable ring.
Has anyone here found a nice elegant solution for this problem?
