Any way to upgrade the head on a Slik 700dx:
 

Hello,

I have the Slik 700dx Pro tripod as seen below:

Slik | 700DX Pro Tripod Legs (Titanium Finish) | 615-900 | B&H

Does anyone know if I can upgrade the head to a fluid head like the following:
Manfrotto by Bogen Imaging | 501HDV Fluid Video Head | 501HDV

I like the tripod stand but I need a better head for panning.

I use the tripod for my video camera (hmc-150).

Any ideas?

Simon
