Okay, for those of you who might be interested in some sort of improved pads for the he400. The powers that be report that the Lawton angle pads supposedly will fit the retaining ring of the he400 stock pad. I am not sure if this is true or not.
It would be great if someone who has a pair could try it and see. Anyway no confirmation on way or the other if any company out there is willing to develop a custom pair of improved pads for the he400, still talking it out for now.
