XP2 Super in HC110B

Anyone had any experience with this? I've seen some samples on the web, and they look like they could be taken for having been developed through C-41..

Dev Times, etc? Massive dev chart said 5.5 mins at ISO 400.

It is a C41 film, tried a normal B&W developer once, much better in C41 IMO.

Questionable in any B&W developer. Harman/Ilford put a lot of engineering for this film in a good C41 development. E.I. 250 and a standard C41 development gives an excellent result. Within the margin of E.I. 100-800 you can use the film without any changes in C41 development. Even with a home processing C41 your results will be much better then any B&W development experiment. And it is an expensive film so why waste it for less quality.

Yeah, any C41 film is possible to develop in BW developer but the result really is not worth it, usually. Mostly because of the mask, you get unpleasantly thick negs which are mess to print or scan.
But as an experiment once or twice, indeed, go for it

I develop XP2 in rodinal, got wonderfull results always!
