Kuzma 4Point vs Airline - is it worth the upgrade?

I just read Mikey's review of the Kuzma 4Point in the September Stereophile.

I am always intrigued by clever design and technology. (I really enjoyed reading and understanding the design of the Well Tempered Turntable and Arm. Also the Garrard Zero 100 from earlier years.) The review suggested that the Kuzma 4Point was innovative and clever in its design.

But for the life of me, I could not understand Mikey's description of the bearing. It was completely opaque to me.

I am glad to find that some of you have some experience with this arm. Can you share with me your understanding of how the bearing is implemented? I am intrigued and itching with curiosity!

2 points + 2 points = 4 points

Extra point: HiFi Plus review by Roy Gregory.

jameswei: glad you said that on mikey's bearing description. I read it about 5 times over 3 days trying to figure out what I was missing ! Now I don't feel (quite) so stupid!

It is interesting the polarization on this arm. Some I respect above have a different opinion....I know lot's of variables...but surely not to this degree so I am assuming matching is critical overly ...

Hiho, thanks for the pics ! Now I understand the bearing! So Mikey kept saying chatterless...seems like their can be chatter is this bearing to...maybe he means less via the 3 points in a cup. 4th on a post...

Jfrech: Two bearing points are the horizontal plane and are permanently hidden, and two points are in the vertical plane. The latter are clearly visible and are akin to two inverted unipivots. It's obvious when you see it.
