If I am playing a plain Callaway ball I will put a blue dot either side of the number and another dot below the Chev
Truvis is slightly different in that one side will tend to be the same as above, but the other side will be a single dot above the number and then a dot either side of the Callaway wording - due to how the Truvis pattern surrounds the ball it makes the dots easier to see doing it this way
I usually put my initials on one side and a treble clef (I was an opera singer!) both in red on the other side! However, I just got a dozen vice balls with my 'Canio' printed on them in blue. I'll probably put a red treble clef on them, also!
