Thank you very much for your reply. I didn't intend to limit my job search to these two tapes, but I felt I needed guidance on these two, as I felt a bit frustrated with my lack of results with them.
After posting, I realized I needed to work on my beliefs regarding my job search and job availability, so I did (with Belief and then prosperity). I felt much better than I had for long while - able to take on the world or as if something had been "unblocked".
I will definitely try TTW or SL before writing any cover letters/job applications in the future.
I will also try LOA in the way you suggest.
Thank you again. I think as much as anything I just wanted to get a lot of thoughts off my chest :-)
