I too have the Manfrotto 055XPROB tripod. Not only is it sturdy but the centre shaft can be lifted up and swung sideways to get a camera down to ground level. Some tripods don't allow one to get a camera to ground level.
I have a couple of heads ,the quick release pistol grip 322RC2, and the 804RC2 head which I prefer for a couple of reasons The pistol grip one won't get the camera in some positiond due to the design where as the 804RC2 has a 3 way head and a huge bonus it turns 360% with a calibration scale, absolutely essential for those panoramic shots where the camera has to stay on the same level plane. I would definately say the 804RC2 head is the one to go for.
When deciding about tripods couple of things to think about, do you want a walkabout lightweight or a heavier studio type. Second I alway recommend testing a tripod fully extended to see how steady it is when taking a photo, camera shutter slap can actually make a feeble tripod fully extended move. So when looking do take your camera and try the tripod in this position.
iThe Manfrotto 055XPROB is one the heavy side which is an advantage if being used on a windy day but
not an all day walkabout tripod
