So, yesterday I forgot my diabolos (3 Finesse G1's) in a hot car all day. When I remembered where I had left them, and got them out, I noticed they were a little softer than normal. Not thinking anything about it, I started diaboloing.
Sadly, it seems that now, some of the cups are a little misshapen. I suspect the heat made the rubber a little softer, soft enough to become misshapen. Has this anyone else? Any suggestions for what to do now? Maybe I should just use this as an excuse to get some G2's?
