Knowone has mentioned Ortofon. I use the 309D and am very happy with it. I have'nt used any other 12 inch arms though. An additional advantage is it's (relatively) low price.
I tend to agree that the theoretical advantages of better tracking, can be outweighed by the by the mechanical problems of controlling resonance and rigidity, with a longer arm. As with so many other issues in HiFi, it is the execution that matters.
