I was a fan of the 180 but not now. In the other side and with a vintage cartridge when the cantilever, stylus tip shape and dampers are changed the cartridge will performs with different performance quality levels.
So you can choose boron but you can choose by material too that by its characteristics is better than boron. It's just an election, both can sounds good but I don't know for sure wich one can have higher quality levels.
Regards and enjoy the MUSIC NOT DISTORTIONS,
