The 12" Jelco SA-750L is actually 2.5 grams lighter in effective mass than their shorter arms. The specs are 10.96 g with the standard counterweight, and 10.80 g with the heavier counterweight. This is without a cartridge. They are oil-damped, if desired. A fine arm with precision bearings, at an affordable price. That said, my dream tonearm might be a Moerch, but they're expensive.
