Michael,
Yep... I mark my AVXs with that alignment mark... and I use that putter as well.
I have found it helps me to set myself properly square to my target - the misses are all poor green reading and/or pilot error!

PS Also put a little fat "J" under the number, just to make sure!

I’ve been doing the same task! I have a 2012 Golo S so I use a single alignment line for lining up putts.

Years ago we used to line up the name. But these thicker, bigger lines I find to be too distracting, especially when playing from off the green.
I just have a plain logo to id my ball.

Just a simple couple of bright sharpie pen dots for me and line that Prov1x up with the scotty phantom ....

Some sharpie dots near ball name and then a solid line through the ball. My coach got me on this and I was able to see the line better. Helps that the putter I have has a sold line through it so able to keep it online.
