For a single via per trace. Multiple vias/trace for
higher current capacity is possible though admittedly
this is somewhat of a brute force approach.

I would agree it is preferable. However from the little
I've researched it appears the required consumables are
somewhat difficult to obtain. Would you care to share
your procedure?
