This may sound mundane, but I would definitely choose electrum. I'm a college student and somewhat of a procrastinator (case in point: I should be working on a British Literature midterm right now). I'm also a musician, and I tend to write my best music when I'm at low points in my life. The ability to store determination, becoming depressed in the process, is essentially always a win-win situation for me. I could store while I'm playing or writing music, then tap my electrumminds when I need to really focus on a project. I also have the suspicion that there's more to electrum ferrings than meets the eye. Consider that in life-threatening, stressful, or traumatic situations, a Pinnacle could essentially tap their metalminds and force themselves to do whatever needs to be done to overcome the problem. I believe this could encompass all sorts of things, including bouts of superhuman strength, speed, or skill, memorization and increased capacity for mental gymnastics, etc. It seems to me that electrum opens up possibilities beyond extreme focus or determination. Unsurprisingly, if I could be a Twinborn, I would definitely choose electrum/electrum.
