Replying to Backflip tips

Hey all :) i know they are many threads about backflips but i havent found what im looking for in any of them. I can easily do a backie on a trampolien without no problems and i can also do it on skiis. but my problem is that my head is looking kinda forward when im doing the flip. so when i approach the lip i just shoot my legs up in the air and flip it and almost bangs my head in the jump. that way i have no idea where i am and i cant spot the landing and its looking very ugly. any tips on how to get my head backwards and kind of get the good look of the backflip? thanks in advance :)
