I have tried, flown, and owned both the Rhino and the Fuels....and I kept the Fuels and sold all the rest. The f-ones seems to fly good, but I have no insight on their durability and whatnot as I have never owned one of their inflatables.
I personally feel that the Takoon bar has a bit TOO MANY bells and whitles on it, I prefer the SlingShot Pro Carbon,..it's cleaner and simpler, but that's just my opinion.
The 2002 SlingShot kites consist of more than 100 pieces, a claim that most other kite companies are just now starting to make. I say..go ahead, go fly them all side by side and see for yourself. While you are at it, take note on the construction of each kite.
