Cartridge (other than Rega) with Rega RP10

Modern Rega MC cartridges actually sound very good - not at all like the original Apheta.  Popular non Rega choices here in the Toronto area include LOMC designs from Dynavector, Hana, Ortofon and Clearaudio.

I recent heard the Ania on a new P8 and it was stunning.

Has anyone put a Lyra on the P10?  I'm thinking about a P10, but with something better than Apheta3 and know people who love Lyra.  (Is it a given that the arm would need a shim installed? I think so but not 100% sure.)

Dynavector XX-2 should be nice choice- will need a shim.

Dyna has been recommended to me too -- but some people wax poetically about Lyra!

I have a Benz Micro SM on a newly acquired RP10 that I moved from an RP6.  It was/is beautiful sounding.  I had the original Exact 2 on my RP6, then a Sumiko Blue Point #2, then a Goldring Eroica LX and finally the Benz.  I called the Sound Organization and they advised to not shim, regardless the cartridge.  They said it was not necessary.  Being a little OCD kind of is in our nature as audiophiles so I get that...but I also don't like to waste efforts.  Does installing those shims simply make the user feel better or are people actually getting sonic advantages?
