Do You Write Aces on the bottom of the disc

When I first started disc golf about three months ago the only way that I seen people wrote their aces was on the sign at the tee.  When I started throwing regularly with some local pro I noticed that they wrote theirs on the bottom of their discs.  I only have one ace and I wrote it on the bottom of my Buzzz.  I was just wondering what everyone else did

I've always written the hole#, course, date, and if there were witnesses or not.
