Fleib, it's all relative. My highest compliance cartridge is a Denon DL-S1 at 14 cu - the FR-64fx I've got works well with this cartridge mounted in an Orsonic headshell and the small counterweight. Great cartridge for choral and chamber music, etc. When I want more body, I switch out to an Ortofon Synergy SPU and the W250 counterweight, which takes the effective mass up to 30-35 g, (more like an FR-64s). This combination also works well - sounds like a Koetsu with iron cajones !!
For flexibility in compliance matching, it really helps to have a removable headshell arm with light and heavy counterweights - the FR-64fx is still one of the best !
