I recently installed the roofing filter in my FT1000MP and also noticed that 
the noise blanker does seem to perform a little better.  I did adjust the IF 
settings in menu 9-1 and this receiver is really quiet now on CW with the 
cascaded 500hz filters in line.  I didn't notice it limiting SSB or AM very 
much, and a call to INRAD confirmed that it shouldn't have as much affect on AM 
or FM reception as they first though.  Worth the money in my opinion, now I 
just have to find a contest to try it out in.
