For me it is PP#1.

Using of PP#3 caused me to loose the ablity to monitor the lag. In fact until I visited Yoda I rarely felt it. During my session with Yoda, we used a small piece of stretch band to practice using PP#1 and extensor action, the feel, etc. After that, about 30 minutes of continuing into the lesson, Ah-Ha, what is that I feel on PP#3?

Just an unscientific observation/comment/opinion, I think that most golfers would benefit from the use of PP#1 for extensor action and in grain PP#3 for monitoring, at least until they have developed sound mechanics into feel.
