Discipline (book) for a Toddler BOY?

My DS has always been less emotional and less likely to throw tantrums, as well as being more patient than my DD.  However as he has gotten older, redirection no longer works (this kid has a super memory) and he thinks any discipline we do is a game and just laughs!  He has also starting throwing more tantrums and being more aggressive with his sister, us, and the dog (hitting, biting, throwing stuff at us). 

I think all of this is typical behavior for a boy his age, but as a parent I need more tools to deal with it.  Besides reinforcing 'gentle' and doing logical consequences, any other recommendations?  What about another discipline book?  I've heard good things about Playful Parenting.

I've read Love and Logic and implemented some of the techniques like offiering choices, showing and feeling empathy, parenting with action (i.e. no multiple warnings, no empty threats) and logical consequences.  Although I like the book, I don't agree with everything in it especially the leaving the child behind in the store if they throw a tantrum, locking them in their room for any period of time but particularly for an hour or longer, or not offering them food later if they refuse to eat the meal in the time allotment you gave them.  These feel wrong to me, so I won't implement everything in the book.

The parts I do like have worked wonders with my DD who is very emotional and impatient.  She can be easily redirected as well.  Our life is much easier with offering choices and showing empathy for our DD.  This has been true for her since about 12 months.  I just wish the discipline worked the same for both of them!
