Like any effect where a little memorization is involved you have to really want to learn it and it will come to you a lot easier. To be honest this effect and the memorization involved is a peice of cake and well worth the tiny bit of effort involved. I literally had this down after a few practice runs through. This is most definately not a complex stack, the force can be dummy proofed with just a few words even with the most difficult spectator and the shuffles, if people can't do them really they realky shouldnt be into card magic.
