Finally took the plunge to get another set of triggers, the Yongnuo YN622C. They have quite a bit of features that I was interested in, where my current remotes were not capable of: Hyper Speed Sync (HSS), ETTL, Manual, Mixed Mode and Focus Assist.

The YN622C came in pairs (2 transceivers) and costs less than $100, which was also a big factor before investing into a new system!
