Thanks Aaron, that's what I figured and went ahead and submitted the 2048.
   Appreciate the feedback.

     I am paraphrasing from what I believe was stated by Larry Bolhuis on
     Midrange-L.  In short, 2048 is sufficient and 4096 will consume (a lot?)
     more CPU to do the encryption/decryption.  He recommended going with
     2048
     and that's what I've done this past year.
