Generally a lot more power when you unhook compared to a c.
What sets a c from other kites, is how the rider can set a c kite to a speed and maintain it while unhooked as opposed to other kites that gain power while your unhooked.
Just try it. I ride a kite that is designed for race/freeride and I unhook no problems, You just have to work out how the kite behaves when unhooked.
Run your bar on suicide since you will be letting go a lot in your first few tries.
Make sure you are away from other kiters and have fun
