Expiration Tolerance of HP5+ Sheet Film?

I just picked up 3x boxes of 4x5 HP5+ sheet film (75pcs) for a good price. It was a good price because it expired in May '07. Yes, it has been kept refridgerated and yes I'll be tossing it in the freezer when it arrives. With 35mm and 120 b&w films I've never really had an issue with expiration dates prior to exposure (post-exposure is a different story). In fact, the PanF in my 6x12 filmback expired in April of last year

Here's the question: due to the difference in thickness between sheet film and roll film due I need to be more wary here? I mean, with development there are sometimes differences because of the thickness. :confused:

Thanks!

Hi Brian,
I have been using 4x5 HP5 that expired about 8-10 years ago.
Looks as good as the current stuff. No problems at all. The base fog is small.
You should have no problems with your 07 batch.

Should be fine. I doubt any deterioration has started, given the cold storage.
