I fly professionally, and enjoy the simpler parts, as well as the more complex ones.
Approach the pickup with a slow descent at pickup speed, hook out (toss it after takeoff, or on the downwind). Don't fly between the poles: let the hook do that. Apply power and climb. Don't come close to stalling the airplane.
I've heard people describe dramatic and exciting pickups and drops, and it really isn't. It's more like a normal approach to land, but a bit higher, with a go-around. Little more. One flies a little slower than usual with the banner behind. There should never be any possibility of stalling, no dives, and no flying between poles. Even the pitch after snagging the hook is nothing more than climbing enough to keep the banner from dragging, and if it's layed out properly that takes very little climb at all.
