In terms echo magnitude, there is no difference, print through is print
through, but due to the difference in pack diameter, the time skew of
the echos is different. Of course, the exact timing depends on the
tape's linear speed. If a loud layer prints through to a quiet passage
and the loud sound is fairly coherent, it will be more annoying than
print through of diffuse ambient noise. As far as pre or post echo is
concerned, the annoyance will depend on the situation. Generally, I
prefer post echo, but any distinct echo is an annoyance.

I've never observed a significant print through problem with cassettes.
(But I've never been a big fan of cassettes and I don't hold them to
the same standards as reel-to-reel. I do marvel at the improvements
over the years, but I relegate cassettes to "convenience" and try to
ignore their faults. During that "ignore" process, for me, print
through disappears.)

Yes, print through is the least of their problems. Proper spooling
could have prevented edge damage, but binder bleed is always a problem.
Mould can also be an issue. Old tape splices are a major problem
because the splicing strip adhesive migration is more aggressive than
the binder. I've seen too much clear office tape used to splice
magnetic tape. One creative type spliced his magnetic tape with a wrap
of painter's masking tape.

OK
