I once owned THAT exact combo, in my Dahlquist days,and really enjoyed it.Go for the Blue Point,as the "Widow" likes that kind of cartridge.
Best of luck

Actually- The weight of the cartridge is not what's important. The Black Widow is a VERY low effective mass arm, and needs a high-compliance cartridge. The Blue-Point(at 12x10-6cm/dyne) is considered a fairly low compliance cartridge. Here's a good treatise on compatibilty: (http://www.gcaudio.com/resources/howtos/tonearmcartridge.html) But then- That's science and physics, which don't ALWAYS apply when it comes to audio.
Rodman is right, not only is the widow ridiculously low mass,it is also a double knife edge bearing (like the early SMEs).These were once thought to "chatter" if too low a compliance cartridge is used.Most moving coils would be out of the question! Over the years I found the Shures (type III or newer),ADC XLM,Sonus Blue,Empire 2000 EII, B+Os,and AKG P8 all suitable. This was when the industry was on a "low mass" kick.BTW,you will notice that there are almost no arms available today that are this low mass.You might be better served to look for a used MMT or Audioquest PT,that way you would have more cartrige choices. These are usually available at a pretty reasonable price.The BP works well with the MMT.
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 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 -:)
