So I've now changed what I do, I mark out the number with a color, I extend the brand line into a line across half the ball for alignment on putts, then I do an outline THP "!" on each side of the brand name on each side, so 4 total.
I use Golf Dots and I place them over one of the numbers on the ball. They are super easy to put on and look professionally done. They hold up very well and there is a decent selection to choose from online.
i have a pink sharpie that i found in the drawer i use to mark a line over the model name (20xi, zstar, etc) and under the brand I put btw on so it reminds me that if i make a good swing on it I should outplay any playing partner in my group.
I use two dots on the side of the number then a line through the "PROV1" to align putts. Played a round with a guy the other day that spent 15 min marking his ball. Pretty much wrote a novel on it lol.
