Re: Yard Practice
If making grass leaders, make a few of different tag lengths. Shorter tags for long grass, longer tags for short grass. The correct length tag will help approximate the amount of slippage you would naturally get from casting on the water.
I feel your pain about learning to roll cast on land. I wasted a lot of time and energy trying to perfect my roll cast on dry land. I absolutely knew I was following all of the video's and books correctly yet couldn't get a roll cast out for beans. Luckily a friend saw my struggles and suggested I practice on water. Shazam! What a difference!
