I think CuCl for a novice is too much. It requires more fussing,
effort and chemistry skill to get going. Its not impossible but AP or
FeCl are much easier to start with. Given all the other things they
are learning, anything that makes the first board simpler to produce
is a good thing.
I've used all three and recommend AP for the beginner as it is
non-staining and you can see the progress of the board. Both CuCl and
FeCl are pretty opaque and cause stains.
After the novice has gotten TT or photomask techniques figured out,
they should then consider CuCl. Given that it has a positive
implication for the environment, its worth moving to.
