The 'traditional established and viable' system only applied to the old imperial scales, and those haven't been manufactured since the 60s or early 70s. I'm not a Luddite and I have no problem with "we're now metric, get used to it". However, I *AM* against heavy-handed bureaucratic methods, and feel they're only appropriate where someone is - for their own personal reasons - waging a deliberate 'war' against something accepted by society at large. At least Luddites were fighting for their jobs.
