Pro-ject RM-4 cartridge recommendations

Does anybody know if the Grado Reference Platinum cartridge will have the same hum problem on my Pro-ject RM-4 turntable that it does on teh Rega tables? any info is appreciated. Thanks.
Any table with the motor under the platter could be a problem for a Grado. But sometimes you get lucky and don't have any problems.
I think the cartridge might be too much for your arm also.
