I actually put the thermometer in there after I went in the trunk one day and noticed how cool it was in there. After monitoring it for several weeks I felt comfortable leaving my extra balls in there during tournaments.
Plus, if it was weather, what would the chances be that both balls would crack in the same place even with different pin positions? DV8 never questioned it but said I was the first they know of to have two crack the bridge. The way it was stated gave me the impression that there is/was a known issue with some of the cover stocks on the Revenge.
