12 inch Graham Phantom

It isn't the length that counts, it is how you set it up and use it.

My wife told me I wasn't qualified to comment on the differences between a 9" and 12" length.

I heard that Holmes Audio is offering a 14" tonearm.

I'd worry about rigidity at that length.

Is there a pill that can increase tonearm rigidity? I need it to last for as long as the music is playing.

I would think that any improvement is minor. I changed my VPI arm from the 9 inch sig to the 10.5, and the change was insignificant. I would think that the arm mass increases with length, and even if the rigidity is maintained, the biggest change is in the mass of the arm.
