There is a thread about APX25 vs. Tech Pan(last answer Oct 18, 1998) that has some info on this.
I've used tech pan as my exlusive 35mm B&W film for almost 10 years and I provided soom info there. Also some 120.
Although I'm no expert on tech pan, it appears that I have had as much experience as anyone answering on these forms.
You can e-mail me for details.
