What cartridge on your VPI prime?


I own a VPI prime, I installed a denon 103 R and I had never change the cart due to lack of funds. Now I want to upgrade my analog ring to the same level of my digital.
I have been considering based on reviews.

1- ortofon quintet
2- charisma MC2
3-ortofon black
4-kiseki blue.
5- rega alpheta 2.

I would appreciate any inputs from your end about cartridge selection and phono associated currently I am using graham slee reflex M.
Kind regards and thank you.

I have a Classic Signature with the same arm, platter, bearing, and motor as the Prime.  I also have the Denon 103r which is good for the money but the 2m Black is fantastic with this arm/table. I am using the phono section of a Mcintosh C1000.   I have heard good things as well about the Quintet.  No experience with the other carts. 
Well, none right now. I just picked up my Prime on Friday, went to mount my Ortofon Cadenza Bronze and found that none of the mounting hardware will fit on the thicker headshell of the Prime. Hardware was fine on my Scout.
So I'm now waiting for new hardware to be delivered.

What is your budget? Maybe check out an Audio Technica ART9, they are getting a lot of love and seem to be reasonably priced.
Hey John if you want I'll trade you, the 2m Black with fit as is:).  Let us know how you like the Cadenza Bronze, it's on my radar.
