I think in a few years volt-nutting became like those wines estimator and start to say ...
1745 is a bad week
1743 is good week excellent with noise but a little bit of drifty, temperature coefficient is the lowest registered ever.
The 1741 is the excellence: very low noise, good solderability and the lowest drift ... those references leaves a slight smell of cinnamon on second layer of the PCB and do not fear mitigated temperature changes. Keep at temperature of 40°C before using, but better served at 50°C.
