Definitely a bit on the stingy side from my brief testing whacking my own arm with the one I'm keeping for myself. Adding metal beads to them makes them a lot more thuddy, which I prefer, and I want to make some like that at some point, but I don't have the beads yet. The person who showed me how to make these things had one with beads on it that I was definitely admiring, so it's a plan.
