Hi! I also had a lot of trouble with not catching an edge while on the flats. It was maddening because when you fall there is no slope to get going again. I really found that if you keep on either edge, you will not fall. If you are trying this and still falling, then you are not on your edge enough. It takes a little bit to get to the point when you can feel your edge catching. Now, I just kinda ride flat on my board and only grab an edge when I feel one side catching. If you want to go down it toeside, just stay on it more than you think you should. It may burn your calves for the time you are on the flat but better than hiking or killing your tail.
