Ashbory uses Silicone O-Ring material, yes.

But I should think the concept is much the same, the longer scale length that John has incorporated would make the pure Silicone strings a bit of a flaccid problem, but the weedwacker stuff solves that quite nicely.

And, both are nonmagnetic solutions.

Which is why my query regarding pickup on John's creation.

I'll reserve my reason for asking that for after he answers.
