The reason that I am interested in a linear tracking arm is mostly due to the fact that I had one on my Delphi, and I was quite pleased with it. I originally had an RB300 on it, and upgraded to an ET2. There was a noticeable difference to say the least. I guess that I have fallen into a linear tracking mindset. I will however explore all the options before making a purchase in the higher price range for an arm. It seems to me that it would be better to gain knowledge through forums like this, than from a magazine review, or advertisement.
Thanks all,
Paul
