Flute Wing Skin J-Stiffners?

After dimpling the wing skin J-Stiffners, i note they have almost a whole hole width (3/32") of curve in the centre. I am thinking that this could apply a force on the skins when it get pulled into position by the clecos.

Should these be fluted slightly to make them straight? (or are they supposed to exert some force onto the skins?)

Here are some images with a straight piece of tube aligned with the end holes.

I didn't

In my -9 wings I didn't flute the J-stringers. There seemed to be enough flex in them to get the cleco'd & riveted to the skins without too much problem.
 
I just did mine. Didn't need to flute ands went in without problems. I would trial fit it and see how it looks.
