Rob,
Given the low effective mass of your arm, 8.5g, you will need a cartridge with a compliance of ~ 12 x 10-6 cm/dyn and mass of at least 8g. Your current Sumiko fits this requirement.
The Sumiko Palo Santos Presentation I recommended will not work, its compliance is too low at 8 x 10-6 cm/dyn. Also none of the Koetsu carts will work as they are low compliance at 5 x 10-6 cm/dyn.
In all these cases the resonant frequency will be too high.
Dan's recommendation of the Ortofon Cadenza Black will work nicely.  16 x 10-6 cm/dyn and 10.7g.
Tom
