I just got my 7075 Supernova a couple days ago, and had the 2012 Supernova for a couple months. So far as I can tell, they’re nearly identical in feel, though the 7075 feels a little heavier on the string. So, I prefer the 7075. And, I prefer them both over the Genesis.
Every new trick I learn will start with the Supernova. It’ll spin forever and won’t tilt while I’m fumbling with what I’m supposed to do next. I still have a loads of fun with my other throws though.
