Your milage my vary in the UK, but if I remember correctly, here in Germany balls only have to be on the conforming balls list if the comp announcement explicitly says so. This is generally the case for pro tournaments and amateur tournaments of a certain level, but not for club comps. This is explicitely encouraged by the official rules. Nobody gives a rat's ass about model and manufacturer, as long as the ball is round, has dimples and has the right size and weight. That allows you to play x-out balls and balls from smaller manufacturers who just do not bother to get their balls on the conforming balls list. And I am sure that ruff-driver's balls, genuine or not, do fullfill the specs, even if they are fake.
Just checked, it says the same on the randa website.
I can't really get my head around what you've written there.
The rules, Appendix III, clearly state that the ball must conform to specific requirements as laid down by R&A / USGA testing.
Titleist balls are checked and have passed, hence we may use them.
Cheap fakes that have Titleist written on them have probably not been tested to be conforming, hence they are probably illegal for any competition play.
