I think the Supermarines will shred. The cone shape keeps the bubble density in the top very tight and uniform. The wide bubble plate provides excellent turbulence reduction (even with the cone, but as it turns out, this restriction doesnt act so much as a nozzle as you might expect). The greatest height from the plate to the top with the new design... and this design allows for much higher air flow rates/density than others... I can see that. Beyond making a taller version of it (which comes with its own advantages and drawbacks), I think this will be the skimmer design to beat. This is the one I would put up against the larger ATB cones, FWIW.
