Fun puzzle! I love that you can squeeze a final quicksilver out of lead by combining it with the previous lead, that's some fun tech. 

This is a variation of my first working solve. I wasted a TON of time making a solve that only uses 1 pipeline, but it was surprisingly bad. That confused me initially, but I think I'm just not used to RI. The instructions are the same if they're on 1 arm or 2, but by making a 2+1 pipeline I don't need to do wanding regrab tech, and can make each hexarm do more.

I think that my top pipeline is pretty solid, but the bottom is noticeably rushed. I'm not sure what I could have done better... but there's no question that somehow I could have done better :)
