My 2 cents worth of "wisdom" on Cub takeoffs is the incorrect slamming of the throttle from zero to full throttle in one micro second. This upsets the path the airplane will take even before you get started. You're chasing the plane right from the start. The correct way, especially with Cubs, is to gently feed in throttle to get the plane moving and continue to progressively feed in more throttle while controlling the direction of the plane with rudder. At the beginning of the takeoff roll hold a little up elevator to hold the tailwheel on the ground for steering control and as you began to pick up speed release the elevator to neutral or near neutral (maybe a very small bit of up elevator to prevent a nose over). Once the tail is up you are steering it with just the air passing over the rudder and by now you should be at full throttle waiting to gain enough airspeed for safe take off. Don't rush lift off, especially with a Cub, as you can easily stall on take off, and then you will have your hands full trying to recover from a stall when you are only 36" off the ground ! Been there and done that.
