After a couple weeks with the Sonic 3, it is easy to say that some of the features of this kite would be great on the Soul:
1. Thinner profile - reduces drag, improves inflation, and improves setup and pack up.
2. Replace tiny white lines with the stiffer gray lines in the bridle.
3. One inflation valve, since two would no longer be necessary.
4. If possible extend the wind range.
Those 4 changes alone would make the kite so much better.
