Replying to I completely lost the ability to Cork 7

I had my cork 7s flawless with grabs up until about a month ago. Then, i started experimenting with tweaked safeties and i really messed them up. Everytime i try to cork 7 i do an ugly 7 that is barely inverted and sketchy, it looks stupid. Is there any way i can just start with a clean slate? Or any different ways of setting it you could recommend? Everyway i try to set it i go off axis (barely) and spin to 810. I tried starting over the whole process of learning corks but it didn't work...
