I have the foot straps mounted just behind the beam. I can use them for my rear or front foot. I mounted them using 2" OD washers and thru bolting them. I bent the washers to the shape of the hull.
As far as the downhaul and rotator I haven't moved anything. I never seem to be adjusting them that much other than shifting gears. I never play the downhaul. I set it and forget it unless the wind or seas change. The mast and sail on my boat will spill off wind automatically in the puffy conditions.
This worked from me a this year nationals. The only difference in the 4 boats that finished ahead of me is that they all had male crews who were running the mains.
The self- tacker is a great option. It allows for some incredibly fast jibes
