So I've been shooting H5X, Credo40, Elinchrom Ranger for years (A heads). Just picked up a set of profoto acute 1200s with the Pro D/4 Heads. Using skyport triggers - it seems the profoto flash duration is MUCH slower. Check this out. Full power on all (1100 on Elinchrom, 1200 on Profoto).
Edit, looks like that's it, at full power the profotos have a duration of 1/560
