I've used YNZ on my '38 exclusively. I did a price comparison between YNZ and Road Island & found YNZ to be a bit cheaper (about 10%) while still excellent quality. That's been several years so I don't know if that's still the case. I've not heard of Vintage Wiring so I can't say anything about them good or bad. My recommendation would be to do an apples to apples price comparison before making up your mind.
