I hope you can help me out with this decision. I have a Manfrotto 055 tripod which I use in the studio for my Hasselblads. It has been so far equipped with the Basic 3-way head with quick release plate 141RC. After a few years of using that combination, I decided that some gripes that I have could result in getting a new head. - The plate doesn't seem to hold perfectly still - The plate even screwed tightly does not hold the Hasselblad perfectly, especially with heavy lenses and when tilted, the camera tends to loosen up and shift position. - The movements of the axis don't seem smooth enough even after being lubricated with gun oil. I've tried a ball-head (486RC2) and didn't seem comfortable. But maybe a bigger one would. I've looked at the special hexagonical plate Manfrotto has for the Hasselblad and understood that I need a new head for it. It is an expensive investment and I don't have the luxury of trying it out before buying. So, my question to you is: - Will the hexagonical plate hold the camera as tightly and steadily as it should? If the answer is yes, I will probably go for the Pro 3D Head (229).
