You might try starting with MILD, which is a technique that covers most of the bases for both WILD's and DILD's. As Gab already sort of said, after you are comfortable with your MILD skills, choosing to attempt a WILD or DILD are more a matter of timing than technique: for instance, if you can't practically do a WBTB for WILD, you can always try for a DILD.
