SME 20/3 --- tonearm recommendations!?


Hello Gon'ers - I have an SME 20/3 coming, recently purchased on Audiogon. I'm trying to decide what tonearm will fit the table and be a good match. I considered Graham Engineering but I have a similar setup already (30/2 + Graham Phantom II). The tonearm will be mated with my Koetsu Urshi Blue cartridge. I generally listen to Jazz and classic rock, but also enjoy most any genre. Will be mated to a Pass Labs XP-25 preamp. 

I've considered an SME IV modified (new bearings, new wiring), or one of the Kuzma tonearms. They seem to be on vogue but I don't know much about them (or it they will fit the SME).

Syntax. What is warp wow and how does the geometry of a tonearm's bearings affect this? Tonearm resonate. How do you split and minimize the resonance? Any idea? 
mohawk that is absolutely perfect. It is easy to add mass. Much harder to take it away. There are head shell weights you can get that hide under the cartridge. You add weight until you get the resonance down just under 10 Hz. Get The Hi FI news test record. It is easy to use and you can dial things in as well as any tech. Do not trust the math by the way. Use the test record. There are too many variables the math can not predict. The Kuzma is a terrific arm for the Koetsu. It has unbeatable bearings, the vertical bearings are right at the level of the record where they belong and the arm tube is as stiff and resonance free as they get. Also if you were to get a high compliance cartridge you can always tame the situation with the damping system.
Come on syntax. That one is the runt of the litter. Why not just go for the Axiom? Right up there with your Rolex.
Mohawk, the 4 point 9 will fit perfectly on the 20/3. The wire will come out to the inside of the tower. Not even close. However the 4 point 11 will work wonderfully on the 30/2. I use a 4 point 14 on a 30/12. I have a Koetsu Rosewood Signature Platinum in it. No added weights needed:)
I personally think the best cartridge for the Phantom is the Van den Hul but the Dynavector should be fine. The Koetsu in the 4 point 11 might require just a little extra weight but when you get it tuned up it should be fabulous. 
Mohawk, the Phantom is not a good arm for the Koetsu. Unipivot arms do better with more compliant cartridges. 
Mohawk, The Koetsu is a low compliance cartridge. Pretty much any 9-10 inch arm is going to require you to add some weight to the head shell. I am not sure if the 20/12 will take the weight of a 4 point 11 but it sure will the 4 point 9 which I highly recommend. I have an arm with adjustable VTA and I use it just once when I set up the arm. You will not miss it at all. The SME arms are also fine but I prefer the Kuzma for a number of reasons. Don't forget to get some head head shell weights and a HI FI News test record for set up.
