Reed Petal Direction

[MaximumHP]

Wondering if someone can tell me which way the curve of the reed petal should be on the seat. Concave or convex? I know I've seen a recommended direction on here, but can't find it now. Thanks for any help.

You'll want to place them so that the very slight bow would be up in the middle of the cage.
