my two cents as they say . . . everything is personal tastes in the end.
85kg, Moses 679 wing . . . I ordered a 4m Peak4 but they sent me a 3m and I did not realise. You might wonder how I did not . . . first foil kite ever and I assumed they had sent me a 4m.
I thought it was a bit small area wise when I laid it out and when I used it, it was super fun but I thought that it was a bit underpowered for what everyone had said about the power of a Peak. After about three goes, all heaps of fun, a friend spotted that it was a 3m when I landed it near him. He asked me what I thought of the 3m . . . to which I said, its a 4m. He said . . . then why does it have a big 3 on the side.
So now I have a 4m and a 3m as I decided to keep the 3m. At this stage, the 3m is my favourite . . . love at first flight . . . such a sweet kite if you like a kite that truly feels alive in the air, not to mention how brilliant it floats off the wind. I have used the 3m a lot lately.
After using the 4m a couple of times, I have found that it feels like a much larger kite in the way it flies and turns.
Power wise, my feelings are that the 3m is like a 4m LEI and the 4m could be more like a 5.5/6m LEI but I really need more time on it.
Relaunch wise, I can't comment as I have yet to drop the kite in the water.
Something different to what I am used to is how the Peaks depower with a very small movement of the bar.
Lastly, I had the 4m at what felt like its top end and the kite seems to hold a degree of pull even when fully depowered on the bar.
