ok for the danger problem. So now, what about the height ?
Let's take a classic: Cab switch 7m in 30 kts and 9m in 25 kts, that's their respective official upper wind range, as per cab's website.
What makes you jump:
- rider's speed
- edging hard before jump
- throwing the kite back and above before jump
- good synchro of the previous 2 params for a more vertical pull
- kite pull to stop you straight and initiate the pendulum
1. rider's speed will be slightly higher with the 7m
2. kite pull: 30*30*7 > 25*25*9, slight advantage to the 7m
3. I think it is quite straigthforward that a (much) faster moving kite will allow for a much better synchro. It also allows you to initiate a jump in less time, allowing you to spot the right bump within a flash when riding in the chop for example. Very hard with a bigger kite ...
Well, that's IMHO the theory which explains why smaller kites jump higher. In practice I can say I do jump much higher with my 7m than my 9m.
