what are your cartridge set up go to

Protractor without Pivot to Spindle measurement is useless for those who own multiple tonearms and turntables. 
If your tonearm is not fixed to turntable by manufacturer then your fist step is PS distance check, before cartridge alignment.

PS ruler must be on protractor, just like Dr. Feickert NG, then you can start with PS distance first and after with 3 given methods (on one protractor: Baerwald, Lofgren, Stevenson). This is really the best money can buy, all in one! This is Feickert NG (great quality and price to have all in one).

With VdH Colibri it’s so easy to adjust on any protractor because the cantilever is open from the top view, just like Lyra on Feickert!

Only Feickert will give you 3 alignment method on ONE protractor. Even if you will change turntable or tonearm, or cartridge, you can still use only Feickert with any of them. 

Look at Dennesen and look at Feickert 

This is my Dr. Feickert NG in alignment of Grace LEVEL II Ruby, from the front view it's easy to align by the cantilever. From the top view it’s very easy to align by cartridge body.
