Well not to be contrary with you as I may never get some of your formulas and excellent advice again , BUT
I humbly reply that I would never run film through a roller transport machine and expect scratch free film.
In fact we will refuse to print for photographers on condensor enlargers or will invoke a retouch fee for those pushing film through roller transport.
In the last 20 years printing for others, I cringe when I get film that has been run through these machines for large prints and today I usually turn the work away or at least give absolutely no doubt in the clients mind that the scratches are not my responsiblity and they need to find a good hand retoucher to fix the problems.
And if the UK Pro Labs are using this equipment for UK photographers then shame on them .

Only in Canada you say.

The quality comes from the labs attention to detail, the training & experience of the staff. HAving been involved selling equipment (silver recovery) to minilabs I can honestly say that certain UK chains pay far more attention to training and quality etc than others.
