I dont understand why so many says "New gear is always better or the best" ???
What pure nonsense...
It is only because they have adapted a "I want new things" mania, that they think so.
The evolution has stagnated, and new kites are NOT better, can be much worse for the individual rider in fact.
I will say the very opposite - that with new kites, your level will certainly go down for a period of time
Experienced riders has adapted the kite behaviors so they can do and feel anything inside out without ever thinking or looking.
If you get new kites, no matter if very different or almost the same - you WILL suffer for a long period because you have to "forget" all the old muscle memory and feel, and adapt to a new slightly or very different one.
This is sooooo important in waveriding (I dont know about freestyle but would believe it to be even more important here)
So if you seek new challenges and are bored, new kites are good.
If you want to MAX your level and riding, then go find the kites that suits YOU, and keep them as long as possible
The very same goes for boards.
