My Golf Spy review - 

I found the ER12 to be hugely stable, predictable and accurate. Spider X players should take a long look at the EV12. I can’t imagine you’ll not enjoy the pairing of a familiar shape with the Evnroll tech.
The white finish is attractive. Not that the black finish isn’t. I just found the white more interesting. Initially, I was a little bummed that the white EV12 had the plumber’s neck. Then I remembered the “V” in V-Series. I could swap the necks! A quick wrench session later and the white EV12 had a slant neck.
That neck swap was easy and this, too, was quite satisfying.
