Polarizing filters.

[Bill]

Well kids, it's just about that time. A little birdie has told me that 
the D FA 50/1.4 is going to show itself within the next few days, and 
will be released into the wild in the next few weeks.
With this in mind, I will be in the market for a 72mm polarizer, and as 
the 50/1.4 is going to be so sharp that brand new Dozuki saw blades will 
look like rusty butter knives in comparison, I feel I should be looking 
for a fairly high quality one.
I know B&W are great filters, but are there any others that I should be 
considering?
Also, what is the difference between a Kaesemann polarizer and a regular 
circular?

Thanks in advance.
