What happened to the Zamperla Mixer and Rotoshake?

I have never seen either of these rides in person and limited information exists about them (especially the Mixer). I only found information on two Mixers and five Rotoshakes in operation. Does anyone know more outside of what is on this flyer? https://newsplusnotes.blogs...-1996.html

Knoebels had a mixer in the '90s called Axis. It was mostly just uncomfortable hanging upside down against a hard restraint. I think there was also a crotch bump. It was fine to do once or twice, but wasn't anything I needed to do every visit. I don't recall there ever being a line for it. I imagine the park decided the juice just wasn't worth the squeeze and removed it.

I thought TT2 was the new rotoshake?
