The ADOX film advertises its single layer as an advantage in image quality but in a figital work flow, that becomes a disadvantage IMHO.
Tri-X and HP5+ are still around as well as many of the same chemicals you used 20 years ago. If you are comfortable with those films, you can still shoot them. The 400TX available today is not the
exact same formulation as Tri-X 400 of 20 years ago though.
It probably would be a good idea to shoot some rolls of whatever film you choose prior to the wedding to get some experience with it again.
