I Flush 8s,
I'm going to take a stab as I have been told but may explain things differently by accidential mistake and hopefully Billy or Carl can correct me if I am indeed wrong...
Take the 505C Ball, the "05" stands for the intermediate differential of the ball and the letter "C" stands for "controllable reaction". The first number "5" stands for 500 series which is mid-performance
The 715A Ball, you have the "15" standing for the intermediate differential and the letter "A" stands for "angular reaction". The number "7" stands for 700 series which is mid-performance plus.
Finally, the 930T, the "30" stands for an astounding .030 intermediate differential and the letter "T" stands for "Traction". Then the number "9" stands for 900 series, which is Track's new high performance category. Plus with the "MICA" additive I believe is a low load of particle...again, hope I'm not mistaken with this...if so, please correct me...if this is the right way, then hopefully this makes it easier to understand for you dude...
Thanks and God Bless!
