If you want even smaller and fits inside a daypack horizontal - Gitzo Traveler series I have a G1550T. Feisol also makes one like this with the 180 deg fold back design to min the storage space and MeFoto does too I think. Mine folds down to about 30 or 35cm with the ballhead, b/c it folds back 180deg the ballhead is next to the bottom of the tripod leg. 2lbs all up. You can also fit a more decent ballhead like the Markins Q3 and you can utilise the L bracket etc.
