I have had a SME IV, use to sell the Zeta, have several 3009s now and had a Transcriptors Fluid Arm 40 years ago. The MMs would be better in the Transcripters and SMEs and the MCs in the Zeta and SME. Since the mass of the Zeta is 16 gm and the SME V is 11 gm [off the top of my head] the lower compliance ones might do better in the Zeta. BUT the best combinations will depend on the rest of your system and your taste. With this many combinations it will take considerable time and effort to establish which is best for you, no one else can tell you.
