Boat is responsive and very stable. It is as fast as a non racer would ever need to go. It moves efficiently with a comfortable cadence, and doesn't feel like it is dragging at low speeds. The rudder is great for the wind and steering on rivers. I know rudders aren't for steering, but if it is there I'm using it.
If you are undecided between boats, save your money and get the QCC. Better yet, wait for a used one on their site.
Stop worrying about demoing every stupid boat. Especially if your live in a place with limited kayaks. If I bought local I would only be able to choose from a tsunami or a tempest. In the end you are never going to know until you own it. The worse thing that happens is you have another boat.
I will say that there customer service is fine, but I'm confused by their lack of emailing. There company is primarily on the internet, so..... I am still waiting on an answer to three attempts at an email. I know I could call, but now I'm just being stubborn.
