HistoryHistory
Testing started in 1996 (8 years ago)Testing started in 1996 (8 years ago) With reactive shell- want more hookWith reactive shell- want more hook Since 2000 we have been working to Since 2000 we have been working to
get the epoxy ball further down the get the epoxy ball further down the lane!!!lane!!!
Modified Epoxy hooks more in oil Modified Epoxy hooks more in oil than than anythinganything to date to date
Can hook way too early in heavy oilCan hook way too early in heavy oil Have built and tested over 900 ballsHave built and tested over 900 balls
