Chad Long's Now Look Here has been around for a while, but has recently been re-released complete with the cards and a DVD. It's great to see Chad perform this several times for a live audience and then settle down for a complete explanation.
Two versions are taught: Chad's original handling and also Scotty York's variation. As a bonus, Chad explains David Williamson's Top Change and Daryl's Convincing Tilt.
It's a very commercial effect, not difficult to do and is probably unlike any other routine you already do!
If you like this plot, I highly recommend Gary Jones' Kickback 52 from the 52 vs Joker Project DVD. I've been using it for quite a while and it always gets a great reaction!
