What's a good cartridge for infinity black widow?


I need to know of a good cartridge for a Infinity black widow tonearm. I will be using it in either:

A. Kenwood KD-500 into a Audio Alchemy vac in the box.
B. Kenwood KD-500 into a Audible Illusions Modulas 3A.

I would like to use a Sumiko blue point, the weight seems right, though Im not sure about the rest. Thanks

Thanks so much for the imput, I have ideas's now as to what cartridges to look for. Is this hobby fun or what?
I wouldn't put FUN as the first word to describe this hobby. Expensive, frustrating, disappointing, and tedious all come before "fun". I am a private pilot...another "fun" hobby. It's only "fun" after you've landed at the place you wanted to without denting anything.
I really have to admit that the "Widow" was THE arm that got my juices flowing(and my money)about analog "coolness".

Before "that" everything was the latest DUAL table.Not that I was not happy.

Btw,on the gorgeous KD-500 it looked SO high tech.

I wonder how the combo holds up today,as these were gorgeous products.....back in my Dahlquist days.When I had hair -:)

Best.
