Hi, you may also want to consider the SAS survival flick book.  It is kinda hard to find, I got mine off e-Bay, but, it is waterproof, and has most of the major components of the full SAS survival manual ready. In addition it is also written by John "Lofty" Wiseman.  It is a little odd in shape, and it fans our like a deck of cards, all attached at one corner with a plastic holder.  The size is 0.45 x 2.44 x 0.91 (inches) and is 110 pages.  There is a write up of the book here on equipped at 
http://www.equipped.org/books.htm#SAS2 .  Once again, I have to agree with Doug's review of the book.  I was impressed with the information contained within, and keep a copy in my BOB, I would carry another in my "man-purse" for daily carry, it is just a little too large for that though.
P.S. Congrats on that exam
