MOTM

I'll need to pick up a MOTM format filter soon.  I have some in other formats, but none in 5U.  My favorates in the other formats are the Mankato I have in frac and the cwejman dual mode and livewire Frequensteiner in euro.  However I'm looking at finding something a little different for my MOTM format filter.  I've especially been looking at the MOTM 410 and the MOTM 440, but welcome any other suggestions as well.
 
I'm mostly doing Noise/Drone in my solo shows/recordings, and also playing with a Doom Metal band doing drones and Hawkwind like psychedelic sounds.
