OK, I think I have decided on what I will be going with.
Another SKB Medium Trap Case!
I plan to have some padded bracing that I can add to secure the pedals fully set up. Once I have that done, I can allocate extra space for a few other items, but no heavy cymbal stands or tom mounts. A bit excessive you say? Pshaaaw...
I think it would be cool to have a sleek case In some sort of assembled configuration, but options are limited. I can get one for about $150, so while it's not cheap, neither is replacing expensive double bass pedals.
