Not all bits, the 0's, due to friction on the sides, might be slower, while the 1's are slimmer, but since they have edges they might get stuck in the bends (but on the other hand they are good at cleaning the pipes).
I worry sometimes that AWS sometimes runs out of 1s and begins quietly replacing them with lowercase Ls. I can tell the difference, but not everyone can.
