If I were you I wouldn't run stage 7, I would just take a one week break from subs and allow the programming to sink in before you start OF. I'm going to be starting that as well when it's released, but I'm going to run it for 3+ months.
I'm not sure what level your fears are at, but with most subs to see any meaningful and lasting changes you need to do it for 3 months minimum. This is especially true with OF since fears are one of the most difficult things to remove going by the journals of people using it.
No one has used this new program yet so we don't know how it will compare in terms of speed and resistance that it brings up.
After that you can decide again what you what to do
