I can see that its nice to have some portable gear, I don't consider my main case Portable cos its Blooming heavy but I'm working towards having a my Top Case and Percussion Case as being portable and easy to combine with a Beatstep Pro. This leaves my Main Case to be more Generative and experimental.
the original 6u case looks really portable to me...
I've had my mantis on planes, trains and buses many, many times with ease in the past...
