I don`t fly a foil on water, YET, from what I read and the little expirence I`ve had flying foils, it is all about personal preference.
Have a look at "www.foilzone.com", they seem to love the new flysurfer speed above all else but I think the Venom may run a very close second.
The best thing you could do though is hook a with your local dealer and try out the different styles of kites for yourself, other peoples opinons are just other peoples opinions.

Fly the kite that feels best to you not what others say is the best kite!
