TT, 12" Tonearm. Who tried and ended up preferring 12" arm?

I don't mean to start a good, better, best, 'here we go again' tech talk about 9/12, that has been covered, and I have been researching.

I am just wondering: Who tried and ended up preferring a 12" arm?

Aside from all other upgrades you probably did at the same time, which could have improved a 9" arm, what about the 12" arm made you stick with it?

I suppose, 'I tried 12" and went back to 9"' would be good to know also

thanks, Elliott

I’ve gone through too many tonearms to list, beginning with the old Garrard articulated arm, through Transcriptors, VPI, Unipivot and Graham. For a while, my vote went to the JMW Memorial 10.5-inch arm for its price, straightforward setup, ease of adjustment and use, but on my current turntable I went with an an Apparition 12-inch arm from Analog Instruments (New Zealand) and I'm not looking back.
First, assuming you’re doing the installation yourself, the geometry defined by the longer arm makes initial setup and adjustment much easier and slightly less critical. Second, the cocobolo wood arm tube does everything it’s supposed to do regarding vibration/resonance. Even with my midrange Shelter cartridge, the sound is pure and absolutely clean. Since my table was custom-designed and built, there is no plinth. Instead, a 70-pound solid brass pillar supports the tonearm; positioning is infinitely variable and, once set up, it’s virtually immoveable. The Apparition is a very simple pivot design that is not without caveats (the dimple in which the pivot sits is subject to wear and mis-placement), but what it lacks in sophistication it more than makes up for in ease of setup, use and quality.
In short, I'm a member of “the longer the better” club. I have no experience with air-bearing tangential arms but, given the choice (and with the room for placement), I would go with a 12- or even a 13-inch pivot arm over a 9- or 10-inch arm any day.
12-inch tonearm made of cocobolo must have very high effective mass. Fine for low compliance cartridges. Not so fine for high compliance ones. There is no single best length or best material for a tonearm.
I have to err on the side of Lewm regarding dustcovers.
I will be blunt and state I have no idea what causes the difference but playing with the dustcover in place and then with it off is akin to lifting a shroud on the music.
It sounds corny but it is more open and dynamic with dustcover off and this is from THREE separate tables.

I use the dustcovers for two reasons.
To keep dust off the tables when NOT in play.
To provide a nice resting place for my tired old cats who otherwise would sit on the darn platter I am sure! 
Everyone knows dustcovers down close in the sound. :-)  I found that out on my LP12 back in the 80s.

Metal lids do the same thing to tube preamps.
