Just ride waves like you do on a waveboard, regarding the kite - just a bit higher.
Meaning, you fly the kite around in your bottom turn, and back in the cutback.
The advantages with the Peaks are they drift amazing, so you can get slack lines now and then, without issues
You can also park the kite at 45 degree or higher, and slalom on the wave surfaces - again, you can ride a lot deeper this way, than with any other kite, especially LEI are pretty useless for this.
I have never seen or had a Peak "ball up" as you say?
Did you ride totally slack lines, or?
My point is, riding waves full on around bottom turning and cut backs, fly the kite like you would on a waveboard (here you, in most conditions, fly the kite aggressively and low), just dont fly it as low and aggressive when on a foil - subtle turning in 8's on top of the window is usually sufficient, and one does that without thinking.
Flying in 8s on your backbone, while turning around on the wave, Peak4 will just drift whenever needed, and you can ride a very free path down the line, EXCELLENT
If you assume you can let the kite hang, and ride waves all the way around bottom turning and cutbacks, I think (know) you are wrong.
The smaller the kite (higher winds), the easier it is, and with a 3 you can sometimes do it just drifting.
With a 5 not possible to the same extent, but way better than other kites, using soft 8s on top - easy and safe.
Going up into 8 m2, it is almost not possible at all is my experience - but now we are talking 8 knots of wind maybe 9 max 10 (for the average weight) usually, so not just the kite which makes DTL waveriding close to impossible.
My take on this at least.
