Anyone know the difference between the Polaris button and Doo button secondaries? I'm gussing the sheave diameters are pretty close of not the same. I know the overall helix diameters are the same, but are the ramp heights (not angles) the same? Does any one now the sheave angles?

I believe the sheave angle on the Polaris clutch's is 28 degrees but don't quote me on this.

Yeah the Primary sheave angles are 28 deg overall. But, I think the secondary is 29 or even 30? Not sure. I'm wondering about doo's secondary angles are though?!?
