Drill a blue hammer urethane for a ball below your low flare.
Yeah its what I was thinking about doing, always wanted a Urethane anyways.
Here is what I would suggest, and someone who knows more about the finish, correct me if I'm wrong.
Definitely go with the new Blue Hammer, or if you have the money, time, and patience to look for one, find a good condition Fab Blue Hammer.
IIRC (and again, correct me if I'm wrong), the Fab Blues were at either 600 or 800 grit Abralon for the OOB finish, whereas the Blue Pearl Hammer was at roughly 1000 to 1500 with a pearlized coverstock.
The New Blue Hammer is at 800/1000/2000/4000, so it will be a lot smoother, and probably somewhere between the Red and Red Pearl Hammer if you were to compare them (dullest to most polished of the original line was Burgundy - Blue - Purple - Black - Red - Red Pearl - Blue Pearl - Pink).
So taking the New one down to 600 or 800 grit should put it close to the original Blue, which will definitely be under the ALF. If you want anything underneath that, you could either play with the surface of the Blue Hammer...
Or drill up a really strong Taboo Spare or True Blood. So you do have a couple of options to fit underneath your ALF.
