Dear @ateal: Thank's to your patience you found out that 150, good .
Now, you can make serious quality improvements in what you have: as you can note the cantilever/sttylus holder build material is not exactly the same in the 180 and 150, where the 180 is less resonant and this means lower signal degradation vs the 150. It makes a difference for the better.
So you have the alternative to send both to Northwest for he can make the change in the 150 to the 180 holder or better yet that Northwest takes the cantilever/stylus from the 150 and put in the 180 holder.
Of course that you have to ask Northwest if they can do that work, my take is that they can. Only an opinion.
Regards and enjoy the MUSIC NOT DISTORTIONS,
