Travelling light with lights...

I'm sitting here at Pearson with a few hours until my flight and thankful I'm a NEXUS traveller allowing me to skip the crazy lines and get through security pretty quickly. Heading east into the cold winter (although Toronto is in a bit of a deep freeze at the moment), and looking forward to doing a bit of street photography. 

This trip, I'm travelling pretty light (considering my love of options) and have decided to take just my 5D III, 50mm 1.4 and a Westcott Ice Light along with a bit of cinefoil (since I don't have any barn doors) and a gorilla pod. Will I even use these? I am not sure at the moment, but I wanted an option to hopefully get a few portraits while bumbling around the city and my preference is to always add light when I can.
