Calibra is right : I was refering to shorter back lines knot setting for the ''more power setup''.
For the front bridle attachment point, I've been riding the factory setup : I'm pretty sure it's the faster setup because as I said previously, this kite is very fast for a 17m.
Thank you Calibra for the indications for the Fat Lady front bridle setup because it's not in the user manual. I've been looking the 2013/2012/2011 and nothing.
I'll drop an e-mail to Blade to let them know that riders read these manuals... or sometime maybe ... when they have questions on setups. If they can't put everyting in the manual, they should at least add info on their web site.
