I personally went with your option 2. I spoke to VPI extensively before making the decision. The new Aries 2 is better than Aries 1 with SDS, but you can still benefit from SDS which should yield better pace and bass. JMW 9 is more rigidly coupled to the base than JMW10/12 because there is no on-the-fly VTA. That rigidity translates to more details and ambience. Also, the bearing and low counter weight (standard on newest JMW9) make JMW9 the best sounding arm in the JMW family. This is not my word, this is from VPI. If you tweak the arm further by some resonance control device and replacing the internal wires, you will have a world class arm at a very low price.
BTW, Aries + JMW9 is called Aries Black Knight.
