Okay, I have done a search of the forum and read what I could about tripods and heads but I am not sure if I understand the difference between different head types. The tripod I buy will be used in many ways. I live near the shore and will be using it at the beach and also around the house and for some hiking. I have narrowed the legs down to the B/M 3221 or 3021 or the Benro C-228. At this point I do not need it to hold a lot of weight but I would like to avoid replacing it in the near future so I would rather pay a little more now. As far as heads though I am not sure what I need (or want). Is it just a matter of personal preference. Or do people use different types of heads for different uses. I am not really sure what they mean either. If someone could point me to a good resource that describes the different head types and how they work I would appreciate it. The ones I am referring to in particular are ball head (which I think I understand just by looking at it), pan and tilt and I think I saw one of the Manfrottos on B&H that had a "3D" head. Thanks for the help.
