do it the clipshift way with a little misdirection.
If u dont know the clipshift, then i suggest the classic pass or dribble pass.
Or heck, just learn every pass out there and do them all , I wanna be able to do that. heheh
Or if u want to do it a complicated way, do the molecule - 900 spin (in mid air) - to the jackson 5 - to a lethal X to a twisted rain - to a mayhem - to a revolution cut (5 times) - to the 8 packet leno cut - to the Full Nelson....pass...... it's pretty easy, all u need is practice
What is the situation that you need to control a card for? I am a pass junkie but I rarely if ever use it to control a card. I think there are plenty of more practical ways to get a card to where you need it.
There is no need to add in dribbling the cards or riffling the corner while learning the basic mechanics. It just makes the move more "obvious." Learn the classic and learn it well. Do it until it is not only quick and invisible, but also motionless and silent.
Then you can add in spreading the deck or dribbling the cards.
However, if you need a pass for a routine, and there is no other way to control it, the turnover pass seems to be the easiest. Just work in front of a mirror for an hour or so to manage angles and get it looking right, and you'll have it down. Turn over the deck without the pass, then with the pass. Strive to make them as similar as possible.
Good luck and don't get frustrated. It's taken me almost 3 years to get my pass where it is.
EDIT: For the record, I am a HUGE fan of Trespass. It is killer. Bottom line.
Classic pass is killer and all you would really need. Misdirecting a person away for a few seconds is such simple act, they wont know what happened. I also like the Spread pass though when I feel up to it.
