I have had a few production lessons, only going into Manchester UK. carrying my laptop and my soundcard in a Targus laptop bag bought from Argos here in the UK.

when going manchester I had my headphones (audio technica m50) in my small rucksack, and my soundcard either as a bulge in the laptop bag (nothing damaged by doing this) or my rucksack.

I found my laptop is a little heavy on my shoulders though.

I will be going to london later this month to visit family, and I would like to take my laptop in order to get on with some producing ect (I only use headphones to DJ/produce)
I will be using public transport (ie the tube/underground) to get to and around london.0

I am after a trolley type case to put my DJ/Producer items in, as I will use my bigger rucksack to put clothes and wash bag in etc.

requirements list for trolley case:
- Laptop, chargers
- few vinyl (say a couple of traktor control vinyl and any random real vinyl I find in london))
- Soundcard (traktor audio 10 or scarlett 2i2)
- cables
- tablet
- possibly a small controller but not got to needing to take one anywhere. (probably my pair of Xone:K2 or perhaps my Launchpad pro)

What is out there, and what would be recommended?
