I've noticed that there is a very heavy emphasis here on using WILDs to attain lucidity. Is this what most people find easiest? Or is it the infamous SP that people want to experience (which you normally won't experience with other methods)? Or, do WILDs yeald the best results?

Personally, I've had the best success with MILDs. I've never actually achieved lucidity, but I came closest with the MILD technique.
