I agree. Anyone who says .010s don't sound good on a flattop has never heard my '72 G37 with D'Addario .010s on it.Re using an .010 set on a flattop, I use them on all my acoustics. It’s my preference given my light fingerpicking style. I of course still have to like the sound of the guitar, and if it sounds good with .010s, you can pretty much be assured it’s a stellar example of the breed. Added bonus: You’ll probably never need a neck reset!
AND the neck is in great shape after 51 years!
