Search for Mint on these forums. You'll find many dozens (hundreds?) of very satisfied users, including many who use JMW arms. The improvement vs. the stock protractor that came with my TriPlanar was (cliche alert) equal to a component upgrade. One of the best investments I've made.
I agree with Kehut in general. You might try putting the metal weight ABOVE the headshell instead of beneath. That will certainly change the way resonances behave, though whether for better or worse only your ears can tell. Damping will also help, it's often necessary with many unipivots.
