hi,
i was struggling to get a decent 2 box bag for my babies, but 3 ???
I would suggest a trolley …
when I did my research I brought the original paper cardboard boxes with me to the vendors, and said, I need a little something that can hold these 3 pieces (the boxes, lighter than bringing the actual OT MD A4)
also these things get heavy after a while… so carrying might not be feasable …
when Backpacking these, I constantly run into doors and walls especially in puplic transport situations, hence I figured, a expensive, high Quality trolley, which I could still carry up stairs and steps, but pull behind me…
my 2ct
… thomann producer bag (A4+OT) + elektron bag (MM) = heave and a lot of pendulum motion … bumping into things, worrying about knobs … trying to sit in a bus or subway cart … not really fun
