The HW-40 feet are pretty awesome, but I don't know if those improvements made it into the non-pneumatic Avenger Direct feet. Anyone know?

Has anyone come up with a good way of replacing the foam strips on the interior of the peripheral ring? In the past the strips came off pretty easily and you could just stick on the replacements, but apparently VPI changed vendors so now the fuzz all tears off leaving the adhesive strip stuck very, very firmly to the ring and it takes about a day of scraping at it with a plastic spudger to get it to come off, and then you have to do the next…

You might think I'm crazy, but HW-40s have always had a very high-pitched noise I could hear coming from somewhere in the motor circuitry as long as the motor is running. It's not exceptionally loud or obnoxious but always noticeable and it's always been there across multiple units so it's not a sample defect. Does anyone know whether the implementation of the direct drive circuitry in the Avenger Direct and/or Titan Direct also have this noise? I would imagine they would, unless VPI changed the motor control circuitry for those models, and I don't know why they would have.
