I got to add my 2 cents on the Thruster. A friend of mine handed his 14m to me last week when I was having trouble staying upwind on my Waroo 15m (due to lack of wind, not rider skill
That thing not only pulled strongly and consistently, it was amazingly agile. I would rate the 14m Thruster as having a turning ability similar to somewhere between a 9m and 11m Waroo (I'm comparing to Waroos since that's what I ride in various sizes). It was super-responsive, but I didn't feel like it was twitchy.
I was able to stay upwind better than my 15m.
I gave a big shout out to Eclipse kites on our local forum about the Thruster, as did another friend of mine who "borrowed" our other friends 14m at various times during out trip. The thing was addictive.
Great kite Eclipse!
