With regards to the interchangeable nozzles. Bill, and I'm sure quite a few others, will remember back to the very first White Water prototype that had drop in interchangeable nozzles, albeit in a somewhat more primitive form, but they existed nonetheless, being plastic inserts that sat underneath the central barb.
I had experimented with different nozzles widths, multiple jet points, parallel nozzle slits, etc, etc.
Thing is, it was an experimental tool in order to determine the better "middle ground" across a range of scenarios.
Still, nice to see that something that was done 15 months ago is now someone else's "new and original" idea.
