Vortex Sound Research

I'm going on a work trip overseas and want to bring music with me. I plan to bring a laptop with Ableton and a small audio interface. I'd like some control surface for synths and keys.

I have a Push 2 but it feels just a little too big to pack in my luggage. I mainly use it for drums anyway and I can live with programming my drums. My full piano ain't happening. Maybe a Keystep? A Roli Seaboard Block might be cool? I'm not sure.

What would you bring?
