Pelican hard case with dividers.

[Trever1t]

I sincerely doubt there's any concern, tight is probably better than loose but I never thought about placement like that. Here's mine:

There are 4x SB-800's ( where it used to be 2x 600s and a single 800) strategically stacked on the left side. Dividers between them. I might rearrange things and take another look at how you've positioned them.
