tonearm mass/cartridge mismatch

What would happen if the tonearm mass is too low or too high for a given cartridge? What is a less disastrous mismatch: a heavy tonearm with a light(less than 10 grams) high compliance cartridge or a light tonearm with a heavier and low compliance cartridge? Whould the combination of a heavy tonearm and a light cartridge lead to a lower resonance frequency?
