Cartridge (other than Rega) with Rega RP10


I've had a Benz RubyZ with my Rega RP10 for several years now, a very nice combination. I was wondering what other RP10 owners might be using and recommend, other than the Rega cartridges.

If you know the mass of the arm then you can easily find compatible cartridge, just make sure the dynamic compliance of the cartridge measured at 10Hz and don't forget the mass of the cartridge and screws. Here is the article. I think it must be mid compliance and most likely the arm is mid mass. 
I have been using a Lyra Kleos on mine since day one. In advice from Jonathan Carr (Cart designer) I was able to acquire shims for 3.5mm  at the base of the tonearm. Mr Carr recommended 3.4mm but unless I have shims specially machined, which I may do someday, I figured .1 mm can’t be that crucial with varying LP thickness. 
Something to ponder should you decide on Lyra, I think they are all the same height. But I do find the Rega and Lyra work well together when set up correctly.  Years ago I had a Rega P25 and used a Benz Glider and traded to a Lyra LydianB and found the Lyra much more pleasing.
Good Luck
The Benz Ruby is a fine cartridge. Period. It was fine on my Graham arm, it was fine on Origin Live too. Arms do make a difference. Tables matter. Everything matters. But the idea you have to match the one with the other, where does this come from? Why?
