Location lighting for Phaseone IQ 160

[flyrcairplanes]

I occasionally use my Elinchrom BXRI for location lighting to take advantage of the faster sync speed but it is such a heavy setup I was hoping to get something more mobil. My speedlights don't seem to sync faster than 1/250th without light loss with my leaf shutter. I am using my wireless Elinchrom skyport system. Anyway does anyone know how fast the elinchrom quadra hybrid system will sync with the skyport system. I am open to other systems but already have a lot of elinchrom modifiers

thanks
