Spin Times/Z-diff's for Nighthawk Series
« on: September 09, 2008, 05:26:19 PM »
Anyone have the Spin times or Z-differentials for the nighthawk series?

I know slight modifications were made in density for every "set" of balls but if anyone has exact numbers for the following, LMK.

Nighthawk Solid/Pearl
Nighthawk Menace/Menace Pearl
Nighthawk Torque/Torque Pearl

The Nighthawk line (and the related Track Havoc) are all pretty mild asymmetrics by today's standards.  They were pretty middlin' when they were first introduced, but the Z-diffs for them have been in the 0.01-0.08 range, I think.  The current NH has a mid-diff of 0.002".  I think the Havoc was 0.007.

With mid-diffs like that, spin times are probably several tens of seconds.  No 5sec spinners like the current crop of asyms.
