I had a Gitzo 1228 for years and loved it. You need a medium sized ballhead for that tripod. I use an Arca-Swiss Z1 on a Gitzo 3-series systematic and it's wonderful but too big for the 1228. Markins make a range of A-S copies and their Q10 is perfect for it. Markins heads are well designed and engineered and beautifully finished. You might also want to look at the Acratech Ultimate, Arca-Swiss P0, and RRS BH-40, all great heads.
