The secret to easy self-rigging is accurate alignment of the wings to
the fuselage. I use Udo's self-rigging dolly (my sympathy's to you,
Udo, about your illness!) w/o the lateral adjustment - not needed in
my judgment (all adjustments I make are exclusively at the fuselage).
I have a DG400, which is VERY particular about alignment. I "walk" the
wing fore and aft to get the lateral adjustment perfect (this is all
done at the fuse). The verticle adjustment is done by tilting the
fuse. I used to do this by having a jack that had a fulcrum that
allowed the fuse to tilt back and forth. Now, I have 2 electric car
jacks that I can run differentially or in unison - this works GREAT
and has immensly speeded assembly!

You have to know what angles are required to fit the wings to the fuse
drag pins, and what are required to put the main pins in (these are
different for the DG400). This is also required for disassembly. When
you have a helper, you just have them keep moving the tip around until
they happen upon these critical angles; you don't have this when you
self-assemble and must know this!
