Losing the hex key on ball weights.

I wear SS donut style weights on my testicles. Always carried the allen hex tool. If I needed to remove or adjust them while out and about. One time, traveling, I lost the only key I had with me. I was camping and had several weights stacked on when I realized I no longer had a key or any axcess to one. Panicked alittle bit, now what am I going to do. I cant remove any of the weights as I had max weights on and too tight to slip a single nut thru to free myself.(thats painful by the way). Spent a long time searching the area looking for the lost key, w/o explaining to everyone what hell I'm looking for. A lot of 'what if's' went thru head. Stupid stuff like what'll the EMTs do if I need help.
I was finnaly able to get into a local hardware store and buy a set of hex tools needed. Whew! That was tramatic!
Ever since then been hesitant wearing weights with set screws to lock. Have a few magnet locking rings, but they do pinch and not as comfortable, but dont need a tool to use. I also found a side slide locking ring weight. No tools required and I dont think they'll pinch or pop loose like the magnetic can do. Ordered 3 from alibaba should be here soon. No more travel anxieties.
