I gotta be honest, that second set of pictures that you put up... the pump actually looks pretty good with what appears to be a softer more diffused glow to the tops. I still think that the tops look a bit cheap - I know that they are not because of the various mold flanges and what not but maybe there is some way to smooth that look out a bit? Maybe tone down the flanges some how. I want to know the flow results as well before I make final judgement.
