I just purchased this effect, which I am looking forward to using. However two things struck me right away:
Ideally, shouldn't the plastic board be opaque - so that the rear "loads" can't be seen through the front of the board (by the audience),after the envelopes are removed?
On a similar note,if the colored envelopes were thicker and/or opaque, then the unremoved prediction slip won't show through it's envelope during the final part of the routine.
Perhaps I'm being too cautious here? Would any Tech. Pred. users share their thoughts?
