mono or stereo cartridge when playing mono Lps??

hey guys...thanks a bunch! my mono lesson for today is very much appreciated.

What do you mean a mono cartridge us "unnecessary"? I've heard a Grado mono trounce a much more expensive stereo cartridge when each was used to play the same mono record.

I heard some good things about Grado ME+ on mono LP. My question is: Grado uses 1 mil profile stylus instead of 0.7 mil stereo stylus (such as Denon DL-102). With 1 mil profile, is it safe to play ALL mono LP from 40's to curret re-issues? For instances: Toscanini's 9 Beethoven's symphonies (NBC sym. oreh.), Frank Sinatra 50s, LP, Peggy Lee's original 50's LP, and S&P 180 re-issued Bewitching-Lee 180 gram LP? Are all the mono LP have the same wider groves that won't be ruined by 1 mil mono stylus?

Unless your arm has a removable headshell (god forbid) Lps are pain enough without changing cartridges. You'd need a second table. I love LP's, but digital is somuch more convenient I wish it sounded better.
