I have narrowed down my choices to 3. Slik Pro 700 DX, Manfrotto 728 B, or Manfrotto 190X PROB with ball head. I've researched these three are of very good quality but it's only a matter of which one suits my use best. I'm an enthusiast and want my tripod to be firm enough to allow me to take sharp pictures, especially on the long zoom end of over 200mm. But at the same time I will take it on my travel so I can't afford it being too heavy or it will defeat my purpose. Thanks for any advice.
