So, strangely, I ended up doing my first PVC nozzle modification on a CPS 1700, I always thought I'd do it on something else like a 1200 or something, but that's how things go, unpredictable. I took pictures of doing it and will post it on my site soon. I also made 3 nozzles which were just the size of the 1700's 2 original nozzles, as well as one the size when you screw off the selector, which is around 15x. I also to give little power boost put on 10 balloons.
I still need to add a handle to the pump, and also give a better test. But even though it was getting dark I still managed to test the smallest nozzle, and the result was great, really juicy and punchy stream. I look forward to completing the testing hopefully tomorrow, and getting stream shots/videos soon. Looks very promising though. What is also cool is how I've also got a spare CPS 1500/1700 nozzle selector with switch now as well which may come in useful.
For now though, here is what the near finished product looks like.
