After digging around here for a while, I decided to pull the trigger on the Thomastik Superflexible Solo 4/4 43 set of strings and tune them to orchestra pitch. I just wanted to say thanks to everyone that recommended and posted about them. I'm surprised that they don't get more love. They seem like a great low tension steel string option. I'm loving the feel and tone. I've got them on a Eastman VB80 bass with the bridge set up 8mm to 4.5mm-ish E to G and they are perfect for pizz and slap very easily.
