<p>I'm interested in the Elinchrom ELB 400 but am having a really hard time understanding the difference between the Pro Head and the HS Head. I read this article https://fstoppers.com/originals/fstoppers-reviews-elinchrom-skyport-hs-96769 and http://www.elinchrom.com/learn/hss-hs.html?key=768dz8dad123edcah7w463 which were pretty helpful but am hoping that you guy can help me understand the downside of the slow flash duration of the HS Head.<br /><br />I definitely want to shoot outdoors in bright sunlight with a wide aperture and still be able to balance the sun with a fast shutter speed. Also looking to shoot portraits as well as editorial and some light sports like a runner or cyclist. Thanks so much!</p>
