I'm thinking of buying a new head for a tripod. I have been using a ball head and I am happy with it, but I am curious about the pistol grip. When I bought my tripod this type of grip didn't exist, so I am afraid that I am clueless. Supposedly, it makes maneuvering very easy, but are there any annoyances? For example, I can see that a large grip can be more difficult to carry or fit in a backpack. Any other thing? Is the grip strong? Does it get loose after some use?
In summary, can anyone tell me about the annoyances and benefits in practice?
EDIT: I guess that I didn't emphasize that I am looking for the "small details". For example, if someone is considering buying a ball head I would tell him/her that the head tilts a bit down if the weight is close to the weight limit of the head, no matter how much you screw it. I would like to have that type of comments for the pistol grip, please. For the theoretical advantages (true or not) I already have google :)
