wakesurfing?

O.K. so I feel like a morron. Every magazine or online article I read talks about how easy wakesurfing is but I just don't get it. I'm fine with the rope but if I try to drop the rope i've lost it. I have a hyperlite landlock and if I pump it too hard to get speed I dig the nose in and over I go. If I try to pump it lightly the wake just rolls by. What speed should I have the boat at? Any tips? Any tips at all?

thanks
