Or GHS Burnished Nickels. In a set they are usually generally slightly less expensive than D’Addario half rounds, and they are available at juststrings.com in single strings, so you can customize a set.Try D'Addario Half Rounds first (EHR310 are 10-46s), they're warm in tone so good for the jazzy neck pickup work but not too dark if you want to play bridge pickup lead lines. You'll get used to the reduced attack before trying full flats.
Also slightly cheaper than flatwounds.
