After years of Stainless Elites at 40 - 100 (good) and then Stainless Skjold at the same 40 - 100 (better), I now use Skjold 40 - 100 Hybrid NICKEL (great)!!! I had avoided Nickel thinking my skin allergy would suffer but no problems and sound is good. Nice strings. I have 5 sets from him. £20 a go. Opened up my world to Nickel.
My dip into Maxima Gold was an expensive mistake - they seemed very "sticky", but only bought one set and took them off.
Also, Dunlop Super Light were too trebly for for my basic, non-slap (can't do), finger playing.
Started with Rotosound in the '60s, as we all did, but ditched them because of finger and fret damage.
I use Fender Phosphor Bronze strings for my two Electro- Acoustic Basses and they are great.
Never tried flats so no input here.
