Depends on how you define heavy cut compound. I think the key is you need to know the hardness/softness of the clear. With all factors kept the same, the result with m105 between a soft and hard clear can be very drastic. Rotary + M105+ LC orange can really screw up a honda with soft clear but merely correct a bmw with hard clear.
Just give PO203S and PO106FA a try, it is very difficult to know a polish without hands on since you will be using it with your preferred tools, techniques, pads and the type of clearcoat you facing with.
