I agree completely. I personally use a round piece of wood about two feet long. I would add that you can really do the repetitions four ways: with palms up and palms down and then twisting the piece of wood (and raising and lowering the weight) both towards and away from you.
If you left weights, do cleans and jerks and reverse grip curls - they help a lot. .
