Okay so thanks for all the input guys! I've ordered some D'Addario Black Tapes (ETB92). I also have another question, but didn't want to make a new thread - since this bass is relatively new to me, I would like to go in the opposite direction as well and get some rounds to see how they sound on there as well. What rounds can you recommend using the same criteria that I have for flats? From what I've read here and elsewhere, round-core strings are more flexible and lower tension. So far I found a couple sets that fit the bill:
GHS Balanced Nickels (44-106)
DR Hi-Beams (45-105)
I was also looking at some D'Addario Pro Steels and Nickel Wounds but wasn't sure if the hex-core used was stiffer, and it would be nice to have a .105 E. I think I would like a brighter tone (ie. steel and not nickel) but not a must.
TLDR: Please help me find a nicely balanced set of super flexible and low-tension short-scale rounds. Thanks!
