Iv'e got a couple of nest mate cocks with black NEHE rings on, can't remember right year. Maybe 2010 or 2011. The white writing against the black background seemed a good idea even though some said to me it couldn't be done around that time. Nonsense. To prove doubters wrong I got a fancier from England's north east to send me a pair which he did and I've still got both birds at the moment. Like I say easy enough to read as are white with black digits.
