Nice Review mate, good points on the tuning options of GTS.
I have been riding the 7m GTS and 7m GT a lot lately. love them both.
GT for boosting and kiteloops on short lines

GTS for wakestyle, freestyle and waves.
I Love them both!
The GTS is the most versatile kite on the Market! C/Delta concept par excellence.
You got so many tuning options- its great when you got it dialed down like Wisha.
GTS is an Allrounder that can be adjusted to any style of riding in any conditions.
The GT is the absolute powerhouse of kites out there. For myself and some of our team the STAND OUT DELTA SHAPE KITE. I haven't ridden a more powerful kite than the 7m GT in strong winds!
The GTS got a lot more top end wind range than GT, i think even more than the XR.
It is really the best out of the GT and XR combined..
You have to try the 7m GTS if you like the 7m GT!
