I like HP5 fine, but this is "ho hum" news to me. I bought a 100' roll of the Arista rebranded "Arista Premium" that's actually Tri-X before the price increase for $34.99 making it slightly cheaper than this. Between the two I prefer Tri-X in 35mm mainly because I get more speed out of it in Diafine and that makes that combination my standard for low light in 35mm when "pushed to the limits" TMZ isn't called for.
I'd love to get a great sale price on HP5 in 120 and/or 4x5. But 35mm, yawn.
I find the only time I shoot 35mm B&W anymore is in low light anyway. Other times, I shoot 120 6x6 when I want to shoot fairly quickly and handheld, or 4x5 if I can take my time and use a tripod.
