From what I can see in the rollerblade video, her skills look very good for a 10 year old. While I understand your desire to see her excel, I think (and I am basing this on nothing more then your quick description and those roller blade videos) your daugther is in a very good program.
If the above is true, then it would be very detrimental to your daughters development to have her taking advice from this forum which may be contradicting to what her coach is teaching. There may be the off chance that you may recieve a good piece of advice, but the chances of it actually improving her skiing over what her coach is doing is extremly slim.
There is no substitute for good on the hill coaching....and it appears your daughter has that already....my advice is post your own skiing here, and use this forum for your own development, and leave your daughter's development to her coach...by the looks of things you are going to be needing to ski pretty quick if you are going to keep up to her.
