Westy,
I would go with the factory rubber, I just changed my Compact clone from the Cocobolo type on AZ CZ's to the rubber.
They are just so comfortable, better than any grip out there for comfort.
I have kept my cocobolos for special occasions, Ha, ha.
The compact should be standard CZ75 sight cut, I think the SP01 is slightly different if I remember correctly.
With having the 75 cut on the slide you have many options including combat style tritium sights.
