C'mon... Tri-X is absolutely a pro film. Do you know how many great images have been made on this film, by professionals and the like? Absolutely stellar film and it's deserving of it's reputation.
I guess it's because of when I grew up, but if someone says "pro film", Tri-X is the one I think of. To U.S. magazine and newspaper photographers of the past five decades, the standard B&W film was Tri-X.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
