11g is considered at the low mass end of the medium mass arm range... (mid mass is from around 10 to around 25g effective mass)
At that mass you can probably handle cartridges with quite a high compliance (perhaps 35cu - which would have a resonant Frequency of 8.1hz) - but ideal compliance match would be somewhat lower - 23cu gives the "perfect" 10Hz.
The Benz MC's tend to be around 15cu - and for that arm 14cu is about the lower limit (13Hz resonant Frequency) - any lower than that and the resonance will start impacting on the audible range.
If your arm has a fluid damping option, that would extend the viable range both up and down by damping those resonances.
But like most "rules" there are plenty of examples of good sound while breaking the rules.
With the arm at an effective mass of 11g (assuming that is correct) - the arm is perfect for pretty much any of the MM/MI designs of the last 40 years (including very top end designs like the AT20SS, Empire 4000D, Shure V15V, ADC XLM/ZLM etc...)
It will also work well with the higher compliance end of the MC spectrum....
You probably won't get the best from lower compliance MC's without adding mass to the system. (which is of course easier than removing mass from the system - the quandary in which I am!!)
bye for now
