I did AFI for my student jumps and let me tell you, they are a blast. There are 3 jumps now that i will remember for the rest of my live, and enjoy telling them to others. My 1st tandem, 5th (1st solo) and 19th (pilot chute in tow, cutaway, cornfield 1/4 from DZ by a lake) went swimming to get my free bag hehe. As for backloops they are fun, but the best is when you are able to jump out doing flips!
BLUE SKIES FOR ALL!
