Neck relief

[mikejdexter]

When strung up should there be slight relief in the fingerboard of the DB (a slight dip--not to be confused with a warped neck)--as in a guitar neck? Or should the fingerboard be straight all the way?
Some guitar/banjo makers build in fingerboard relief before stringing up--does the same apply for the DB?
Your thoughts on the issue most welcome.

Yes the same applies to DB, to varying degrees. Too much scoop though and it can be difficult to play.

I couldn´t think of an instrument where you don't need the curve. (Sitar?) The string needs space to vibrate, and more so towards its middle than at nut and bridge.

Thanks for your answers---as I thought, slight relief in the neck is required.
