Re: "Don't use strength!"
If you can't find someone who can demonstrate it, I'm afraid you are going to struggle. The other problem is that you will probably need to take your technique apart a bit, and you will get worse before you get better. Maybe not the best idea if you are looking to grade soon. I'm sure the IS/IP guys know a lot more than me that can help you, but there is not much that anyone can do to help over an internet forum.
