Absolutely correct! Thanks for your input here!
Getting your weight off the tail of the board and having it supported by the rig and driving foward through the mast foot (mast foot pressure) is absolutely key to being
able to get the most from smaller boards.
Your stance also gets a bit more vertical (the fig "7" stands up a little straigher) which
takes some pressure off the fin (you will be using much smaller fins with drastically reduced area) and it's imperative that you transfer that force up to the mast foot.
Hope this helps,
