That's a good idea but there are a few issues. Weight on a disc could change the flight and stability if it isn't built into the design. If it isn't exactly in the center it could wobble a lot more in flight. These do look like they are small enough to add to some of my lighter weight discs. Pinky's almost at max weight as is, so adding more weight to it could be the subject of some angst if my buddies are drinking too much beer or something, LOL. (It's doubtful anyone would really object unless I was playing in a tournament) It could be worth trying out though, thanks for the tip.
