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

In my experience Mortite dries up and is bad for that purpose. You need an ultra high compliance cartridge. Also, the Black Widow was designed for a light cartridge since the arm is easily flexed.
The chances of finding a Sonus Blue cartridge with a rubber compliance that wasn't hardened by now would be very slim. That's unfortunate as it would be ideal for the Black Widow arm(I had one in a Magnepan Unipivot I way back when). Replacement styli haven't been avaiable for those for a number of years either, Sonic Research having gone out of business long ago. Here's company that offers a variety of older cartridges: (http://www.adelcom.net/cartridge.htm)
I remember getting good results with these 'back in the day' with an Ortofon OM30 and OM40, both of which are still available. The mounting, height, weight, and compliance all worked out great for this arm.
Thanks so much for the imput, I have ideas's now as to what cartridges to look for. Is this hobby fun or what?
