Just Teardrop EVERY hold until you finally get it. The TD works every time, and nothing says you can't do it.

Technique:

I tell students to hold up their right hand over the RMI for a right hand hold (or their left hand for a left hand hold). If the inbound course appears above the meat of your palm it is a Teardrop, if your palm covers the inbound course it is a direct entry.........and NEVER NEVER do a parallel, because you'll just F it up. (This appears in a different form in the AIM as a pie wedge)

I had to instruct this during my own PC at the airline to my SIM partner. The instructor gave me 5 minutes to save his career. Both of them laughed when my idea worked.
