Wondering if anyone could comment on the outdoor useable range of the 645DF/IQ/LS with either the V-Air or an AirSync transmitter/receiver combo? Are you able to hit 1/1600 reliably, no matter the distance?

The shoot will be using Broncolor out on the ski hill (hence the Air Sync receiver) and before I go into testing, just thought I'd throw it out to the crowd so I know what to expect. I'm hoping to see 40-80ft if possible. I'll have a few 30ft sync cables on standby just in case.

Sorry if this is the wrong section, but it seemed a specialty to the DF system, rather than a straight up lighting forum question.
