For rounds, Ernie Ball Regular Slinky Medium Scale 45-105 (19.99) also fit ball end to taper on the Starfire and sound fantastic if you are into the Stainless Rounds sound, even though they are nickel plated steel. Massive fundamental and plenty of clarity and kick. Best rounds I have found so far for the Starfires. I do want to try the TI jazz rounds one day though. Where's a good place to get them?
