In reply to beardy mike:
Thanks Mike and everybody for useful replies.
I will take my superlights to the shop i bought them off, see what happens. Will report back.
Doing a bit of testing with a strong magnet, easiest way to check if stainless or galvanised steel , though some stainless is magnetic apparently, I just got some strange results.
Strong attraction to the wires on some superlight sizes but not all.
Older Size 1 strong
Older Size 2 to 6 weak
Newer size 3 strong
Also noticed that of the three size 3s I have , the oldest is smaller than the other two . The larger two are almost the size of an old 4.
Should maybe on the other thread, but also found that some cams have stainless stem wire, some galvanised. Most trigger wires are galvanised.
