Your experience with the Sky Fly is exactly my experience. For a new flyer, its really fast and doesn't respond too quickly. Still with enought altitude its a lot of fun to fly. I decided to go with the Slo V, just as you are thinking about. Its very, very responsive and stalls easily but forgiving. I'm not puckering up while flying it like I am with the Sky Fly.
I think the Slo V will enable me to be better able to fly the Sky Fly since I don't have the luxury of an instructor or flying buddy to coach me.
