For those that wants a real challenge, try fingerspinning on a Protostar. But, keeping your finger loose is another way of saying keeping it relaxed. Relaxed? Have your finger turned up and try to wiggle it lightly. That is how relaxed your finger should be. Believe it or not, it’s hard to start learning how to do it on a Horizon. But after you get it, you can always do it. I personally learned best on my Elysian. It worked great. But, if you really feel like you need another yoyo, look into the Horizon (again), Skyva, Jacknife, Sherpa, Elysian, Curvy Donut Man, the M.O.V.E, and other things like that
