Using WILD in combination with WBTB yields the best results for me. In fact I had success with it last night.
Basically it involves waking up and occupying your mind with something - browsing the lucidity forums is always a good choice.
Set an intention - and think about what type of dream you want to have.
Go back to bed and use the WILD technique to fall asleep with the mind awake.
Hopefully this will be successful for you.
