Balance
Balance is a dock. Radius is the river that has to reach it.
A face-balanced mallet is not morally better. It is a short-basin barge. Using it in a long basin is how you stall.
Joss marks balance on every plot before Wren opens the rack. If you already own a brick and your trace is long, we will say the quiet part: the head is the argument, not your hands. You can change heads or change radius with a coach. The gin will not do both in one hour and call it magic.
