What do you usually do to control a specific card in the deck to the top/bottom after spectator shuffles (let's say you glimpsed their card and you want to control it). I use a spread cull a lot, it's alright, but it is reasonable action during performance only when it's hidden with openly looking for the two jokers, for example. What ideas/methods/sleights do you use besides a cull? (please, do not reccomend any card crimps, I do not want to use them)
