OP’s definition of exotic is indefensible. By any rational definition, Replikant, Gyger, SAS, and Microline, Micro Ridge and Shibata all quality as exotic. Not exotic…all variations of conical and elliptical. Plenty of exotic styli have been made for MM and MI generators. From yesteryear there was Stereohedron by Pickering. The ADC ZLM used an exotic profile. I run a Shure V15 Type V with an SAS stylus by Jico on my Well Tempered TT/TA. With carefully adjusted VTA it traces everything.
