What cartridge are you using with VPI JMW9

Curious as to what cartridges fellow JMW9 users are successful in using. Is your cartridge a match made in heaven or incompatable with the arm?
The signature JMW9 has an effective mass of 9g, higher than the standard JMW9 and is compatible with lighter carts.

I currently use a Shelter 90X with great results. It tracks like a dream. Even my torture tracks.
Did some upgrades over Christmas, (from my post above), and am now running an Ortofon Jubilee with the JMW9 Signature. Very nice and a nice improvement, (as you'd hope for the money), over my JMW9 Karat combo I was running for a couple of years. Cheers.

My friend has this table with an EVOII or 3, can't remember. Sounds very good and he is considering an upgrade in the phono stage. I personally think that he should upgrade to a good MC first and then the phono. I think it will better help him in making the subtle differences in phono stages more apparent IMO. How do you others feel about this. Much has been said about the Blackbird on this table but I can't see it being a huge jump in improvement over the EVO.
Thanks listeners...
Count my vote for the Dynavector 20XH - absolutely excellent. I've been meaning to try a Shelter 501mk2 for an upgrade now that I have a MM/MC switchable phono pre.
