I've got a 391 and never had any problems with excessive buildup on the back plate, and it's had plenty of use.
I've noticed sometimes people like to fiddle with the air filters too much. I don't know why. Leave it alone and let it do it's job.
I'm interested in the flocked filters though. I haven't seen one for the MS 391 yet? If someone could post a link I'd be appreciative.
