The weather in the UK tends to be quite dull much of the time, so I personally have no need of 25 ISO films. So I don't think it would be very honest of me to sign a petition asking for something I would never buy. Now, if they were to re-introduce the 800 ISO film, I would be interested, but I wouldn't be buying much. And the lack of sales was, I believe, why they took it off the market even though it was a well thought of film.
