I would use Seductress at first if it appeals to your goals. Then, every 3 months or so, take a washout from the secondary title and switch to the other. So, in this case, you’d go back to Genesis from Seductress.
That way, you can proceed fast on your shifting goals, then run Genesis to see how you feel overall, then can decide if you wanna run Seductress again or stick with Genesis / run something else.
