Question about psychological force

[HIM#23]

what is the most common and clean method to mentally force a card.
The only good way i know how to mentally forcing a card is by using David blaine method which you riffle a deck and the spectator see that card you want them to see.
There are some methods on Dani DaOrtiz lectures. But couldn't understand perfectly thus cannot perform well.
Somebody suggested Derren Blown's method. Is it worth learning? Any other good suggestion.
coz i wanna create a effect that the spectator think of a card and stop exactly at their by combining the psychological force and the timing force by dani daortiz

A psychological force is either using a carefully worded script to put the idea of a particular thing into someone's mind, or a script that narrows down the choices invisibly. What Blaine does in that trick is not a psychological force, though he does use psych forces in other performances.

The thing is that everyone has to do a psychological force in their own way. If you just copy Derren Brown's script, it probably won't work for you. You have to hone it to your own performance style.
