I've been having a lot of rage moments learning the Shadow 12 lately. I keep spinning and letting go on the pen, but it repeatedly spins no the left edge of my index finger or rolls across the top of my hand. I have tried many times, hours on end, and I still cannot get the proper movement down. Sometimes when I spin my pen real slow, it kind of rests after the .5 rotation, but it's not really fast enough to even be a spin. Can someone please help me with this? Any advice would be greatly appreciated. I guess this may be irrelevant, but is the Sonic basically a twisted sonic on the other side of the finger? I really don't understand it and if you are reading this post and able to answer the Shadow question, I guess you would know this too.
