Curious about Hipshot Transtone Bridge

In searching, I only came up with a paltry two threads related to this bridge.

I'd like to know more about it.

Is it being discontinued?

Has anyone had any experience / success with them?

It is rather hard to tell just by pictures how versatile / well designed it is.

I have a blank P bass body so I can mount any bridge pattern I like. The satin finish of the transtone is appealing.

Pros / cons?

Any info would be greatly appreciated. What's out there in regards to this bridge is extremely sparse.

If Hipshot offered any other bridge in this satin I'd prefer a top loading string design like the A or B, but they both have chrome. I'm trying to get away from chrome with this particular assemblage.

Thanks!
