This is the head I have for my Swaro ATS 80, absolutely love it, smooooth! https://www.bhphotovideo.com/c/product/752279-REG/Gitzo_GH1720FQR_Series_1_Magnesium_2.htmlUnfortunately, they don't make it or it's brother (below) any more, but you can still find them at a decent price if you look around. The link below has the black/grey version available from B&H Photo.https://www.bhphotovideo.com/c/product/709793-REG/Gitzo_GH1720QR_Two_way_Fluid_Tripod_Head.html
