Soundsmith cartridges on Rega tables ??

I'm thinking of perhaps "moving up" from my current Rega P3-24/Exact 2/TTPSU set up. One of my thoughts is a Soundsmith wood body moving iron pick-up, as I've been reading a lot of good reviews about the Soundsmith brand.
How well do they match up with the Rega RB-301 arm (my current arm) or the RB-700 arm (if I decide to swap my P3-24 for a P-5) ? I plan on still running the signal through the built-in MM phono stage of my Rogue Audio Cronus.
