Well, reality checks are my only method. I've created my own RC (expect something unnatural to be behind me, and if it is, I'm dreaming) that works very well. So long as I can nap, I'm guaranteed lucidiy--and the RCs just help me out a bit.

This is true for me; what is true for me might not be true for you. It's important that you find what works for you--if DILD is your best option, then stick with DILDing; if WBTBs are good to you, then do them a lot. Much of lucid dreaming, if it isn't natural, is trial and error. Reality checks might work for you, but they are more likely to need another method along side them.
