I need a tripod that I can get into a rollaboard bag ... max length ~ 21" inside meaning max of 20" or less for the tripod when collapsed. A Manfrotto 3011 with the center column removed almost makes it but not quite unless yoiu nput it in the bag diagonally using way too much room. The only solution I know of is one from Stabil but that is over $600 (ouch) + shipping to the US. It needs to support some 6-8 pounds a bit more hopefully but I am will ing to sacrifice a tiny bit of stability if I can get it in the bag. Sometimes the airlines let me carryon a tripod by itself and sometimes they don't. Usually I can scrounge one at the other end but I would like to find one I can count on packing for my carry-on kit.

What have I missed? All ideas appreciated.
