I agree with the others... new legs. You can not go wrong with RRS, but I have to agree with Sean. I got the Induro CT414 years ago and it is really stiff. I am pretty sure the CT313 would have been sufficient, but I wanted taller and wanted to error on the side of too big.

I see Induro now has a new version w/o a center column that may be stiffer yet, but I am not to sure about the swivel feet they added on those models. It does not make sense... you would buy a tripod w/o a center column for the added stiffness, but then they added three swivel joints (one on each foot). It seems like the benefit of losing the column is reduced or eliminated with the swivel joints.
