Thanks for the input Spruce.
Lots of options will be available, its hard to imagine until people starts to experiment.
Yes Jeff has messed around with overhead jets, and I have as well. I think the important part I am trying to get across is the overhead jets will be much more benifitial without detriment if you can fully control when the water comes out of them, with the advantage of having through the brush jets and again with control.
Overhead only would only need one Aquatap, as you can reduce or increase the flow from it very easily. The AquaTap on its own could make overhead jets much more practical and user friendly than they are just now.
With the Aquatap when your rinsing you could have it turned on half flow while working along the top of the glass, increasing the flow to full as you work your way down.
