Thanks for informing,
looks good to me. Would be nice to hear more about the hybrid concept in the future.
In the context of GIN Marabou and Peak4 water usability, there has also been posted this about 7 years old prototyp from flysurfer:
to me with the main difference it hasn't had close tip cells which could be pretty important for performance as we have seen GIN Shaman and directly Peak3 -> Peak4
On the other hand to me those hybrids still have to show their overall benefit over a Peak4 in the water. On the end FS could also be right that a hybrid is again to much compromise in terms of costs, behaviour, performance, weight ... Very happy so far with Peak4 :
