i have a good memory, but i'm smoking a wide variety of sticks lately... so i write notes on first or second time smokes. if i'm smoking something i already know and love, i might write a review just to post it up on BOTL and share my experience.
I usually only have a couple of any given stick in my humidor (I've only made 4 box purchases ever), so I normally jot a couple notes down in a book. If it wows me, I try to get a 5-er, and make a special note.
No notes just rely on endorphins to remind me which ones to go back to!!! The list is rather short for the humi these days maybe a rotation of 5~6, always open to new things
