sometimes threads are slow, that's okay.
Question though. How much weight does the rubber part contribute to the disc percentage wise? I'm curious because I'm wondering if you just keep the overmold the same weight and change the weighing agent of plastic part or do you try to balance out both?
I'd be very interested to know how much of a gyroscopic effect it would have on the disc if you tried to make the lightest plastic mold possible and focus the bulk of the weight to the rubber rim and adjust that to make weight differences (but I suppose that would make heavier and lighter ones fly drastically different...).
Just some curious thoughts.
