bass FINGER rest

[Talbo]

I wonder if anyone knows... which way is the finger rest supposed to be fitted convex side facing up or concave side facing up?!

I realise this is a pedantic question

Cheers in advance for suggestios!

Depends if you use it as thumb rest or tug bar.....is it top or below strings?

Tug bar...

whichever feels better? I'd imagine it's curved side away from the strings...
