I purchased Questo, despite the price. It is interesting, would work, but is too cumbersome for me. I don't feel that bulky folders are the ticket for a good Q&A act. This is just one of several ways of gathering the information, and there are so many out there. I think that people go for systems like Questo because Q&A, like hypnosis, needs nerve, and people want some failsafe system to prevent failure. Eddie Burke, through his website
www.mreenterprises.co.uk, has a booklet on the Q&A act which goes through several practical methods. It's all you need to know. Combine that with good cold reading and the insights in George Anderson's Dynamite Mentalism and you will have an unbelievable act.
