Hey Group,
I just borrowed this info from the other thread here:
--------------- SNIP-----------------SNIP----------------
Epic Quest
Ultimate Vision solid particle 2%
Purple/Navy/Forest
med/heavy oil
spin rate 7 seconds
7+ inches track flare
1000 Abralon
rg 2.53
diff .052
--------------- SNIP-----------------SNIP----------------
Ok, can some one explain to me the term spin rate and what that info would do for me in purchasing a ball.
Thanks

Spin rate is to measure how fast a ball spin to the PSA. You can find out more by going to Morich site and look into the Determinator section.
So basically the less time the stronger the MB.

What makes asymmetric balls interesting is that they have a strong preferred spin axis (PSA). The PSA is one of the most stable axes that the ball can spin on, so it has a strong desire to change from an arbitrary spin axis to the preferred one. The spin time is the time it takes for such a ball to find its PSA from some standard starting axis.
There's a special machine called the deTerminator[/i] that is used to find spin times. Lower spin times mean a strong mass bias, more asymmetry, stronger PSA. That means the position of the marked MB has a greater effect on ball reaction.
