Replying to Misty 5

Whats up Newschoolers, I have been lurking on this site for like 8 years but I've never done a flip...
I can do Cork 1260's on trampoline as well as flat ground backflips... But I've always been too scared to huck it on skiis.
I was thinking about doing some flips this year to really up my ski game this year. I was thinking that the misty 5 would be a really good first flip because you are always facing the ground, plus I've plenty of practice with them on trampolines. I was planning on doing this off the 40 foot jump at my local ski hill.

Is there any advice before I go and kill myself. Any prerequisite tricks? is a misty too much for a first flip? thanks!
