I have the medium size pedaltrain with the hardcase. Love it as well. The open frame makes cable routing real easy and you can actually hold odd shaped pedals down with zip ties (much better than velcro). Mine has quite a bit of extra room in the case (good for cables, power, etc) but a piece of soft foam (egg-crate or thicker) is necessary to keep the pedals from banging around while traveling.
