Tonearm: Phantom vs. 4 Point vs. 10.5

Pierre...if it's of help, there is a huge thread on the merits/demerits of the TW arm. It's clearly a well manufactured and thought out design but there are plenty of others.
The Phantom, as you say, has a known synergy with the Raven (I use one myself) and is one of the best engineered implementations of a unipivot you will find anywhere.
You should be able to get arm boards for the Raven for the above 2 arms easily enough but with delays of up to 6 months? (Which is quite normal for small manufacturers)

I'm probably wrong but I'm not so sure about a plenitude of Raven/Kuzma 4-point owners(?) It doesn't matter. If necessary TW should be able to create an adaptor or unique armboard but again I would expect a reasonable delay?

Hi Pierre,
As mentioned earlier...

Another thing to consider is the captive arm cable, Pierre...

Electrically a benefit perhaps(?) but not helpful when trying to change the cartridge or merely tighten/adjust the cartridge screws (assuming that we do it the advisable way and remove the arm from the turntable each time to prevent possible bearing damage?)

Also what happens if we snap a cartridge wire? New cable loom? Package and ship the entire arm. How long? Another 6 months off-line?
With a Phantom, plug in or order a spare wand and you're good to go?
Hope this proves helpful.

Often these threads inspire references to the Mint Tractor.
I would expect a protractor to give good tracing of the stylus tip across the ideal arc when aligned but does the Mint detect whether your cantilever & generator are misaligned with the cartridge body or do you use another process?

Agreed! Your feedback would be appreciated Pierre.
I know little about the abilities of the 4point other than a Hifi+ review I read several years ago. It would be interesting to hear what your feelings are on it. I suspect they'll be very positive. :)
Cheers....
