<p>Great choices. I am using a Profoto AcuteB2 600 AirS (344MHz) Pb and a Profoto AcuteB2 600 AirS LiFe for most of my people shoots. Otherwise, for events on the run requiring E-TTL II, I have a couple of Canon Speedlite EX-RT's tethered to a Quantum Turbo 3 Battery and a Quantum Turbo SC Battery. Not the greatest, but it works.</p>
