I recently bought a used Ion3 with the intention of plugging the gap between the 9m Atom and the 12m Atom. The main problem I have is that the 12m Atom is quite a heavy & slow kite so the bottom end of the wind-range is deceptively high. This means it rarely sees the light of day.
I’m also hoping that the Ion re-launches a damned site easier than either of the Atoms do. They’re particularly bad and I’d even go as far as to say dangerous on water as they’re a complete pig to re-launch on water.
In an ideal world, the 10.5m would be a single kite quiver but I can’t see that happening. It may languish in mid-table obscurity but time will tell.
