Bought both the 30mm and 50mm versions to try on my SuperJet. I haven't had time to properly test the 50mm yet, but so far so good. The product feels quality and is very lightweight. Very easy to fit, it took me under a minute. I wondered how a jubilee clip would hold up with the forces coming out of a nozzle, but no problems with that at all, it didn't budge. I tried it at a range of speeds and it had no noticeable impact on top speed or acceleration. It made the steering feel more positive but not overly aggressive. Looks pretty cool on the ski as well. I need more time on the water, maybe around a course, to give any further thoughts, but for the price of the parts I'm very happy so far. The ski setup is stock tuned with VK Composites sponsons and ride plate, and WCOT intake grate.

The best way to explain the difference is that it feels like driving an old car with worn out steering and then having it rebuilt to new. It feels tighter, more responsive, and more connected to the bars. It's worth the money for sure.

The big surprise came from the LUDJET 50mm nozzle. It dramatically improved steering geometry. Immediate change in response in turns and straights. It effectively omitted what felt like a delay in the turn to me. It’s precise in the turns, much more predictable, and much more controllable. The ratio for the turn feels spot on. I do not have a quick steer, just moved the steering cable to the most outward position. I did notice that wide open, straight run feels more planted and linear. I only rode it for about an hour, but I’m pretty pleased with the combination at this point. Nice work, well done!

With it installed it doesn't walk as much on glass-like water which is great. The biggest difference I felt was at slow speed and in turns. You can definitely tell there's a lot more leverage.

Definitely helps in the straights. I'm still experimenting with it.

It's absolutely perfect. Snaps right on exactly.

Fits perfect. Full range of motion.

Fit well. No issues. Stayed on for the ride. Gave extra control in turns and kept the jet in the water. Highly liked. The only thing I didn't notice a change in was porpoising. 10 out of 10!

After switching back and forth between stock and the 50mm extension, I could definitely feel the difference. The ski felt more stable at higher speeds and had more control in harder turns. Fit and finish are great and the quick-swap design works perfectly.

The ski felt much snappier coming out of turns. The harder I got on the throttle, the quicker the rear came around. High-speed turns in chop were responsive and the extension stayed perfectly in place.

I think the idea as a product is great. When I tested it, I felt that straight-line stability improved and the ski felt a little faster.
