They're Grrrrreeeeeaaaat! When I find one, I can tell if it's a new one LOL

I used the limited edition Pro V1s in a tournament on Saturday and found the new alignment arrows less obtrusive than the former black ones.  I do use them to align my putts, and they were fine.  Of course my putting was atrocious on Saturday, but that had nothing to do with the new alignment lines. 

I mark over mine with a sharpie but custom  color options would would be nice.

I agree that the arrows need to be longer too if color options were available.

I too would like it if we could "customize"  the A.I.M. sidestamp (color, length, and width).  I use a red sharpie and make mine a touch longer and wider.

Think they are great, more color options would be good

Count me in as a fan.  I use them to align on the tee box, but not on the green, so the slightly more subtle arrows are better for me.
