I prefer a factory mount or a good local dealer to do the work and check the specs for me. That said, I did purchase the DVD from Michael Fremer on turntable setup so I can understand and potentially get involved in changing cart. I would feel the most comfortable starting with the Ortofon Blue for comparison and then moving forward from there once the difference can be heard. But I would lose the advantage/convenience of having a factory mount. Perhaps the dealer would mount the Ortofon for a small fee or free due to the table purchase. As I understand it the Whest can be configured for almost any load but a call to then is necessary for the settings. Generally how are the MM and MC different?
