While my string choice for an LTD Viper won't be as relevant for actual EB/SG users due to pickup type and position, maybe someone will benefit.
I finally found strings I love rather than just tolerate when I tried D'Addario Pro Steels EPS300.
They are long scale round wounds tapered at both ends, in a hybrid gauge of .043 .063 .085 .107 .
The package says "Super Bright" and that is true for a time, but of course they settle down like all the rest.
Their tone was exactly what I wanted--like Rotosounds but without the rough feel, lively and responsive. They sing.
What impressed me even more was that the volume and tension of each string matched the rest closer than any set I've ever tried before.
They sound and feel the same across the neck, which was a revelation.
Most interestingly, the setup I did afterwards seemed like a lot of intonation adjustment until I noticed that the bridge saddles ended up in almost a straight line that wasn't nearly as slanted as every other bass/guitar setup I had done for myself or my friends over the last 45 years.
Just a well balanced set of strings in every possible way.
I quickly ordered another set for a completely different bass--Ibanez Iceman--and the results were exactly the same.
