I got some free D'Addario half rounds 6 months ago and put them on my #2 bass. Damn it I liked them so much I just went and put DR flats on my #1. I really like the tone. Don't feel I lost any high end clarity. What is a little different is the feel. It will take some getting used to. There's a little more abrasiveness? that is messing slightly with my timing on some parts I've been playing for years. Is this going to bother me for long?
