So if you use a unipivot arm, please share what mass and what carts you have tried and how they compared. I’m using a Nema Unipivot arm and I have compared the following: Dynavector 10x5 Glodring 1042 Roksan chorus black Sure xm97xe w/jico sas AT 33E AT 33PTG II AT 33 SA Truthfully each change was a step up from the one previous. Although the AT33E is probably equal to the PTGII. My arm is midweight. Would love to hear your experiances?
