I bought the Y-cable that lets you use both outlets and by that half the recycle time. I think it's 2.25s with the ad360 with full power, I never wait for it. I use it a lot at 1/16 power and keeps up with 9 fps.I have two Godox branded AD 360's. Viggo is right...get the Y cable. Recycle time is QUICK! Make sure to get the protective covers that really should be included in the kit. http://cameraflashaccs.com/products/bulb-protective-cover-witstro/ Check around on eBay and you'll find them for just a few dollars.
I get very successful high speed sync using the extraordinary Phottix Odin triggers. Godox may have HSS capable triggers by now, no doubt cheaper than the Odins. Worth having in your AD360 kit.
My understanding is there is no difference at all between the rebranded AD180/360's. There may be differences in warranty offers. Mine have two years. Godox is a company that has no problem at all distributing to resellers who choose to re-brand. This may change at some point in the future as the Godox brand becomes more internationally recognized and mainstream.
