i went to marina CP about 2 weeks back and didnt see any 'expensive' tripod there. do you have to ask for it to be seen or its because they didnt have ready stocks?
Yes you have to ask for it... they keep them at the back of the shop.
Ask to see the Manfrotto 055MF3 (Magnesium Fibre - 3 tiers). It is amazingly light, and sturdy at the same time. It will be able to hold your setup without a problem and you don't have to hang anything in the centre hook. I think the damage is about $500+ (without head)
One thing you might want to consider... do you want quick release leg extensions (Manfrotto), or screw type (Gitzo)? Makes a difference.
