Dual CS 721 replacement cartridge.

I aquired a dual CS 721 without a cartridge. While I was searching for the later version of this tt, I bought a Shure M97xE. More recently, I found a new Shure V15 Type III that had never been mounted and picked it up. I am thinking the V15 would be a good match for the ULM arm (does the CS 721 have an ULM arm) and would be nestalgic. I used to use a M93ED years ago. Would that be a better match than the M97? I know the sound would be different. Would I be missing anything that iss really audible? This is my #3 tt (#2 CS 5000 #1#1 SL-1210mk5. Your thoughts?
