RE:  Hella Aim, I found this interesting article which shares your
frustrations when aiming Hella e-codes.  I use Cibie headlights.

"Beam patterns are better (wider, longer-reaching) on low and high
beam with Cibies. The main difference, though, is that 7" round and
200mm rectangular Hellas have an irritating beam separation problem.
Set the low beams where they belong, and the high beams are up in the
trees without enough on-road light. Pull the high beams down where
they can be useful, and the low beams are down on the bumper. I
exaggerate for illustration, but the effect is to make you try to find
a compromise setting where both beams are kinda OK. The Cibies do not
have this problem; when the lows are correctly aimed, the highs are
correctly aimed. Some folks don't find the beam separation as much of
a problem as some other folks--and a lot of people who have only ever
used two kinds of headlamps (Hellas and sealed beams) will swear that
Hellas are the cat's pajamas."
