Double Bass fingerboard tilt

[sq105]

I'm wondering if anyone could suggest a good fingerboard tilt angle.
I read that fiddles are tilted to the treble side 1 or 1.5 degrees, cellos tilted 3 or 4 degrees towards the bass side depending on C bouts and string height. Cant find anything for double bass.
thanks!!

Most makers do not build in any tilt. If you were going to, you would tilt the E side a bit lower to avoid having the bridge significantly higher on that side. But, that might mess up German bow players as they need all the clearance they can get on the bass side.
