Van Den Hul what is the best cart ?

I will probabely buy a van den hul cartridge, but regardless to the price, I don't know what to choose. My dealer says that black beauty gold 0.85mV is a very fine cartridge, but I read a lot of very fine reviews of the colibri.
And about the colibri what should be the best ? copper or gold ? 0.20mv or 0.30mv ?
I've got a VPI aries 3 + JMW 10.5i and for the moment a zyz 4D copper.

Thanx
