Choking the mast! This is def a heavy weather topic.
If your leading arm is up to it then put your lines slightly back as I've found you can get your body and the sail into an optimum position pointing hard. Having lines back and sailing for any length of time on a broad reach e.g. a NM run can be taxing on the body so it's should be a balance between what you're wanting or are doing the most of. Whilst sail trim important pointing, board trim just as critical so as much as it pains to, I really try to keep my front leg straight and hips twisted forward which in turn keeps the board flat through the water which utilises the leeward rail to assist with pointing.
