Saw your post on SA thought I would answer it here.

You are right to have the weight back. You should have footstraps on the transom. I like the back of them to actually be attached to the transom while the front will be attached to the deck...that far back! As the skipper you will feel the spinsheet rubbing against you occasionally, no concern just pointing it out.

You obviously do not want to dig the bow in. If you see that the bow is going too low you can drive the boat down to leeward, while going downwind, to save the bow from diving and your crew from acting as a human pendulum.

Keep the questions coming if I did not answer to your complete satisfaction.
