good advice all around. as a newer kiter (coming on up on my kiting anniversary) I'm still relying on a big, grunty wing to haul me out of the water without really dialing in my kite flying to generate the power on a smaller wing. I'm starting to work with smaller kites and learning to fly 9m kites faster and with proper sheeting to really get everything out of the kite I can. I'm hoping to get to the point where I can foil with a kite that isn't completely depowered the whole time I'm cruising
I found something that said single skins are on the order of twice as powerful as a comparable sized LEI, IDK if that's true, but that would roughly line up with your situation. typical foil kites were 1.5 times a comparable LEI for reference.
I guess it's also a question of what you want to do, sounds like a genesis/peak4 would be a great cruising/free ride/gust-eating kite, where as the higher aspect kites will be faster, more freestyle focused. would you all agree?
The other thing that I like about going with a peak4 is the resale-ability. I'm always a fan of being able to trade something back in if I change my mind in 6 months
now if I can just find someone to buy my 17m turbine and door board...
