I'm sure they rated it, but it was probably around 2000.
I don't think a 5" pin can (or should ?) be used on a Rico drilling. They (Rico) recommend a 2-3" pin for a Rico.
I have had 2 Green Meanies. The first I drilled a simple 4x4, pin under the ringer. It was a skid/flip monster on light to medium-light oil. The 2nd one I went to an extreme, although I was only a tweener at the time: pin left of the liddle finger, CG in grip center (I am a righty). This was much more controllable and I used at Nationals to go down the boards for 2 nice 600s in team and singles one year.
I just picked up another but haven't tried it yet.
The ball was also a carry monster IF (and this is a big "if") you could get close to the pocket. If you have any kind of average release, revs & ball speed, I'd seriously recommend a control drilling (like a Rico) or a 2x2 or a low pin, or a kicked out CG + a weight hole, to control the backend. If your speed dominant or have a release that produces a controlled reaction, then it will be great for light to medium-light oil with a more normal drilling. A 4000 Abralon finish could be a big help to control the flippiness, maybe even 2000 Abralon.
Jw,
YOur ball's 5" pin to CG, together with a 5" pin to PAP, probably allows/causes your GG to take longer to stabilize before getting into a roll. This may be why it handles such light oil.
