I learned using the static line method... it was the only kind my DZ offered. I would say that if you have lots of money saved up go ahead and go for the AFF, because its gonna cost you a lot more. At our DZ, NONE of your static line progession jumps (ie static line, 10sec, 45sec) cost more than $30 bucks. Compare this to AFF which most of your jumps are over $100 bucks.
But I do agree that your first few intial jumps on AFF are a lot more fun than your first few on a static line.
Both methods will teach you to skydive, and let you have a sh*tload of fun.
