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?

Rotoshakes were notoriously difficult to maintain, I am not sure why. I only rode one once, Hammerhead in Dubai, which had been relocated from Knotts.

Quite a fun ride, although not fast, by any means. It was almost a mix between a Weber Traumboot and a Top Spin, in slow motion.

Never rode a Mixer. I recall a VHS back in the day where the Knoebels ride featured heavily. Would have been a no from me ... where abouts was it in the park?

Power Surge took its spot. I preferred that to the mixer.

I rode the Rotoshake at what was then Canp Snoopy at the MOA. It was a lot of being held upside down and not too dissimilar to a top spin. It was OK, but it’s probably the ride torn out of that park I miss the least.
