Correct me if I am wrong. You yourself have stated that you do not need to have both feet on the ground in order to be leveraged. I believe you added the qualifier that it would be "ideal, but not necessary" or something similar to that. Am I quoting you incorrectly, or have you changed your mind about that statement? When I created the clip above, I never stated that it was the ideal launch position.
