VC4 500 Good enough to install hybrid belts?

Hi all,

I've recently finished up a VC4 500 and got the attached response and shaper graphs.

In my opinion, these look to be good enough for me except for some leftover resonance in the 100-135Hz range and close to 200Hz. I left an inch of belt on both sides of the toolhead (in case anything goes wrong) so I have a feeling those are the causing the resonance. I would prefer not mess with the base core xy belts anymore since things like this can begin to spiral out of control.

But since this is my first printer build I would prefer to hear some more experienced opinions before I lock in the hybrid belts.

Thank you for reading
