Oh, well here goes. One of the longest discussions I ever had with Keith was regarding walk-ups in junior. I feel in some circumstances it might be ok to do a walk-up, but that really depends on the setup. If the grounds just don't provide much of a test it might be acceptable, but most of the time I believe it's used when it doesn't need to be. That being said, you should train on it, your most likely going to see it at some point...
