Had considered the strakes would be next, but do a quick mockup of where they would go, and realise it will be a bit tough to reach over them, at least to do the turtleback, so decide to do that bit next.
Mark up the longerons with applicable FS, and the relevant BL on the spar. Note a discrepancy with the seatback, and realise that the seatback being aft 1" will change the position of the TB-1 bulkhead, and change all the FS. Grrrrr. This will require thought, and it is time to hit the net and see what others have done.
