Well what to say, I'm very satisfied with my halfbike: I'm still learning to "ride outside the box" but I can say it's a unique experience. It's a bit tiring but really fulfilling.
It seems a bit like meeting a new friend: you have to relax a little at the beginning, you are a little afraid but you want to show her that you want to know her better and gradually start trusting her more, until running together faster and faster.
Highly recommended!
