Reading around, I stumbled upon quite an interesting statement. It was about different ways to control a card and what it provided (psychologically) to the spectator. More specifically about the classic pass and an overhand shuffle (but it can apply to several others), here'd be how it went: A classic pass allows ye to prove the card to be in the middle of the deck, whereas an overhand shuffle control allowed the card to go anywhere in the deck; thus one should choose according to how the trick goes. So I started thinking on the Biddle Trick. All references I've seen of it call for a Bluff Pass, but (this is for those who actually perform it) if a Bluff Pass shows the card to be in the middle of the deck and, with no extra movement, it makes the card appear near the top, a spectator might presume he did not truly placed it in the middle; whereas a shuffle control might've made it stumble upon that place. Wouldn't it be better to do this with a shuffle control + false cut or something of the sort? (Used the Biddle Trick, Classic Pass and Overhand Shuffle Control merely as an example, for this would apply to loads of material)
