When doing a complete deck false shuffle, I've got a problem/question. After riffle shuffling, and after the "sqaure up", when I'm stripping the packet out to be cut back onto the top, there is a very large amount of resistance, i.e. the packet pulls out cards from the other packet, or, more commonly, a couple of cards get stuck in the other packet. I hope that's clear enough, but anyone who knows how to do this should be able to decipher my ramblings. Any tips, suggestions etc? I'm assuming a newer deck would slide more easily, but how bout with an slightly older deck. Thanks in advance.
