I had my first 17D2 too long, I was also setting antiskate on my RB300 arm to the same value as the tracking weight. Result after a few years was a misaligned cantilever and a stylus that had worn more on one side. Then I learnt about using a blank section of vinyl to set it, on the rega scale it was nearer to 1 than 2 once set like that and no more uneven wear. My next arm, Aro, had 5 notches for a thread and one of them sounded best, easy. My current arm (Schroder Reference) I set roughly with a blank disc and then by ear but my system’s come on a bit since the Rega days, I could never hear much difference back then.
