Corbin, no offense, but I was not impressed with that video. Yes he's using a straddle grip, but there are other factors going on. It looks like he is smearing the cards to make a better take, which again doesn't look normal and arises suspicion.
Of course everyone has their own style and taste. Mine happens to be a deceptive bottom deal that looks exactly like my regular deal. Unless you ALWAYS use a straddle grip, and never change, then I guess it would fit for you.
Whatever grip you decide to use, never change it for your other deals.
