Achad's or Bardon's Qabbalah books, Which should be read with Regardie's GoP Options

Hello folks!

I just finished reading Dion Fortune's book " The Mystical Qabbalah" and have just started reading Regardie's " Garden of Pomegranates". Since the latter book is so thick making it kinda hard to pack around at work and also keep it out of harm's way, I was looking for a pdf that I could print out and take to work not having to worry if it gets fuel on it and ,most importantly, complement "Garden's" and "Mystical's" take on the Qabbalah. The two that I am looking at are Bardon's " Key to the True Qabbalah" and Achad's "QBL". In y'all's opinion, which would tie in better with Fortune's and Regardie's
books or is it pretty much "six of one, half dozen of the other"?

Any guidance much appreciated

The difference between Biblical and Modern Hebrew is negligible, IMHO. For example, I taught myself using Modern Hebrew resources, and first used it reading my prayerbooks and the Hebrew Bible! Some things are different, but it's like comparing modern English to Olde Engliffe.
