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

l have owned a Kuzma 4Point arm for a few years now mounted on a Kuzma Stabi XL2. l have the opportunity to change to a Kuzma Airline and was hoping to hear from members who have heard both and whether they think the switch is worthwhile. There is not much l can find on the net comparing the two.

For a similar cost l could add two motors to my XL2 converting it to an XL4, could the upgrade there be more significant than the Airline vs. 4Point?

Interested to hear fellow 'Goners opinions.

Cheers,
Simon

Jameswei: "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

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 ...

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.

Kuzma dealer.
