Now I have the cube i'm not so sure I need this now. Outside the cube it is the strongest mono ball you will ever buy, steal or borrow. I kid you not this is the best I ever used when it comes to ballheads. This is in great condition except it took a heavy hit on one side and has a nice scratch. Yea its meaningless but you need to know. New these are 548.00 dollars at B&H.
