I had considered building a better solution, but my free time isn't as ample as I'd like and I didn't get anywhere with that idea. I ended up springing for the Pedaltrain PT-2 with flight case and the excellently-matched Voodoo Labs Pedal Power 2+ (which mounts perfectly underneath). At around $330 USD it was a fairly pricey solution, but I have had absolutely no problems at all with this setup and I never even have to think about it or worry at all. I figured with what I had invested in pedals over the years, I should give the lucky ones that make it onto the board at any given time a safe, comfortable place to live.
