I'm sorry, but unless we can see you trying it, we can't really offer any more advice than things that you would know if you read those articles. Go out and ride with somebody who can trackstand, watch what they do and have them watch what you do. Try to copy their movements. If they see you doing something completely ****ed up, they will say "try this, it might help." or offer other critique. Posting on an internet messageboard isn't going to have you trackstanding.
