Pivot arm or telescoping-pivot arm?

We've been brainstorming for the last couple days and aside from our base which is already completed a 4 wheel plaction 4 wheel omni dropped down via pneumatic cylinder driven by a 5 CIM motor chain drive configuration with a very low COG we are leaning towards an arm of either telescoping/Pivot or simple pivot....

Dimension are 36" by 12" for the robot with bumbpers...... we figure we can safely get about 100" of reach from a 3 section pivot arm easily


We listed some pros and cons of each and we would just like some extra input.... If anyone has any of their own concepts or input it would be greatly appreciated.
