Default Paxton Superchargers

Paxton states the optimum CR for their small block ford superchargers is 9.0:1 (like with using the NOVI 1500). Just curious, anyone using a Paxton designed for a stroked 351W (near 427 CID) and with a CR higher than than 9:1, like maybe 10.5:1? If so, how do you like it and did you have any issues with the higher CR? This would be my plan 'B' if I decide to boost and not go the turbocharger rout. My CR is 10.4:1 on a high quality DART 427W build.
