Sunny...found ya'! I did not want to hijack CD's thread to comment on the 5LL book. It is not a heavy tome like War and Peace. To me, the 5LL book is a twin companion to the DB book...it is less than half inch thick. Probably the width of your pinky nail! These books work in tandem when utilizing some of the DBing techniques with the WAS. Especially if there is an OP in the picture...knowing the LLs gives you a leg up on the competition (pun intended!!).
