 experience out there to confirm or deny this?

I have tried such a fixture and had relatively good success.  Part of the
cause was poor design layout, yet this was a mature product with no budget
available for a new layout.  EMC makes a standard wave solder pallet with a
rotatable inner piece that can be set to any angle, and it worked well.
