For real radicial tricks you need time in the air, hence the X2 goes well for this.
C Quads don't perform like a high AR inflatable... you can configure them to sit back in the wind window and give good pulling power for wakeboards... this also makes them immune from luffing.
The X2 still luffs in the flukey stuff... then again all high AR inflatbles are bound to struggle in this stuff....
In interested to see how I get on with the 16 or 18m X2 when I get it... but I'm not intending to use it in 5-6 knots... I'm getting it more for powered up riding in 10 - 15 knots... big air and plenty of time for tricks etc.
I use my 8.5m C Quad for those flukey 5 knots as these kites have more low end than the X2 but the X2's have better top end than a C Quad.
When a C Quad is set up with loose brake lines the kite can be voluntarily luffed. The kite can be depowered and this is the setting used for buggies as it allows better up wind travel. When depowered the kite shoots forward when edged and dumps the power... not good for kitesurfing but can be handy for buggies.
A lot of fun in light winds.. especially when people with inflatable kites have to sit on the beach and watch... and far cheaper than kites like the mastair...
