Good TripodHead

hello!

I am looking for a help to  choose a tripod head!! (a stable tripod head) .

i am using Manfrotto 055XPROB. for now is ok., (but probably should think for a replacement for the near future.)

i have been using for some time - Giottos MH1300-652 and  Its very unstable ! Could you give me some suggestions for a good realible tripod head please.

i use 5d mark3 with battery grip sometime,with lenses canon 16-35mm and canon 24-105mm f/4 IS

Thank you!
