I will meet some potential new bandmates this weekend, and as they’ve been writing in C-Standard, I just set up my Yamaha BB734A for that tuning and can confirm that the Dunlop Standard Series nickel roundwounds in .120/.100/.080/.060 feel great like this.
If you like 60-120 (as I do) you might find the following useful. You might know of all these offerings, or some of them. Don't know about it identifying every set out there.
These are off the shelf sets that have 60 80 100 120 gauges exclusively or part of a 5 string set (There are some 6 string sets with an additional 30 gauge, but I don't mention those.) I only looked at long scale offerings as well. Far as I can tell only Dunlop, Galli and SIT offer a specific 60-120 four string set (marked with an asterik.)There a quite a few 40-120 sets (La Bella contribution is a 118 gauge. Close enough)
The only Flatwound set I came across were the Dunlops. As far as custom sets, you could do Newtone in the U.K for Nickel plated and Stainless , round or Hex Core. Pyramid in Germany for Pure Nickels. You can build a set from D'addario XL singles or get EXL190+ a single 120.
