The passion solo strings on my fiddle sounded good, they were warm and projected well I used a few different E strings to see how it affected the sound,. The Westminster string was the darkest, a lenzner was just a pure crisp sound and the Gold label has a slightly brighter sound than the Lenzner does to me but very clean sound. I just put on the Amo strings form D'Addario with the Westminster E and I am very pleased with the sound, warm and they project well.
Good luck on your E string search, and welcome to the forum.
