I never have had a ball cup pop off in a race or otherwise.. Same set-up for the past 2.5 years. I did put an o-ring on the stud to remove the play in the cup. I like having the same set-up as the team drivers so that when discussing set-ups I can directly relate how my car is set-up with theirs. The stock cup set-up is lighter (especially with an aluminum ball stud - blue is so pretty), and the ball cups are easy to replace. I also hate wearing out the antenna mount, as I glue in the antenna. So in the end, buying a pack of 16 ballcups from AE is pretty cheap insurance.

I'm not knocking your 'bible', however, it makes it much easier to relate with people with the same basic build.
