double undercut, then riffle shuffle. Never been caught out on it, so if it ain't broke why fix it! It is simple so I can talk and not look at my hands whilst doing it, which generally means no one else is either! Also, the riffle shuffle means its very easy to add a couple of cards above the chosen one if you need to for the trick. I have a a couple of tricks where the card needs to be second from the top. If anything, this makes the shuffle more convincing, because even if the spectator thinks the cuts brought the card to the top, then seeing extra cards falling on top it if makes them think there is no way you've controlled it.
I used to like using the hindu shuffle control occasionally, but it's a shuffle that looks odd to most people, so arouses more suspicion than others.
