Lightweight/Traveling Tripod

[ahab1372]

I have a plate on the camera all the time - just changed to the smaller one I have from the Joby Ballhead X, because the one that came with the Sirui ballhead blocks the battery compartment (or maybe I should buy a bigger camera - I kind of have to now, don't I?).
I also have a problem with the collar plus plate on the 70-300L not fitting in the bag. I'll either re-arrange the divider in my bag, or just remove the collar with plate attached altogether and put it elsewhere in the bag - after all, this lens is mostly hand held for me.

Edit:
My plates do not have safety stop screws. Instead, the ballhead has a safety pin that sticks up into the plate and prevents it from sliding out. The camera (Rebel T3i) sits comfortable on the flat plate when I put it on the table, or on both lens and camera plate when connected to the longer lens with collar and plate. Does the bigger body of the 7D want to tilt left/right? I cannot imagine it has much wiggle room.
