There's no definitive answer, it's up to you. Both will work fine, as will 25' and 28'.

Hi Rahoul,

Any chance I could get a copy of those files please? I'd much rather CNC dishes than make them myself!

Cheers,
Nick

I believe ideal radius is up to the individual building the guitar. Many guitars are made with a flat top, while many others have a radius built in. Even a flat guitar has some induced radius once it is under tension
