Bottom line is
Given the cost of the stuff I bought a 30mtr roll of the Xtreme 100, it is a bit soft with a fairly low D-max but is a good 100 asa and works well in replenished D76d made up in 1985 and prints well in my Leitz Focomats to 10x8', all I bother with for snaps - I have not tried it in either of my DeVeres - I may try extending the development when the light gets soft, but as my current snapshot camera is a Retina 119 with an uncoated lens I am not going to argue about its quality - One can make a lot of pix with this film and not worry about the cost
On which subject, and being my own Devil's Advocate, the cost of petrol/diesel, model fees, accommodation, insurance, location hire and all the other things involved with making pictures, the difference in the cost of film should not be considered - Work out what you want a film to do and buy the very best quality fresh film you can get, for me it is Ilford Delta, but that is based as much on my knowing the emulsion as its inherent quality - I don't bother trying other emulsions once I am getting the results I require, apart from the Xtreme for snapshots, but that is a one off, perhaps
I have been using Foma 100 10x8" film, but will return to Ilford Delta 100 once I have used the stock I have - I may even sell the 5 unopened boxes here for a very attractive price
