Grado Sonata and tracking



I have heard unhappiness from prior owners of Grado cartridges that they are poor trackers??? Is this a golden rule, or is it more a mismatch between arm and cartidge? I have a Well Tempered arm.

Cheers!

I have a Grado Reference in an SME 309 arm and the tracking and sound are excellent.
currently using sonata on a vpi scoutmaster and have encountered no problems tracking
I had no tracking problems with my Grado Reference/Reference as long as the record was perfectly flat. But the slightest warp (on my TNT/JMW 10.5 setup) gave it fits. And then there's the mysterious and maddening Grado Wobble to contend with. Two of the reasons I'm much happier with a Shure V15xMR.
