Card Concepts sounds fantastic - I can see it'll be of no interest to many but it'll right up my street!
Ordered it from Davenports last night, it's still £16. (£6.50 UK delivery

) - can't wait to get it.
I've been giving the G-Principle a lot of study since Xmas, trying to get to really know it so I can develop effects using it - I'm sure I haven't understood all its applications yet but already I can see how powerful this thing is - too good to be discussed on a open forum really!
One aspect I'm struggling with is "justifying" the reversal required before the riffle, so any pointers on this front would be appreciated.
The reversal methods I'm aware of so far are:
Count a packet to the table one card at a time (this is the one that needs justifying patter);
Cut roughly half the pack face up before going into any kind of messy interleaving shuffle (ala Lennart) - love this, it all looks just so damn disorderly;
Have the deck stacked with upper half reversed, cut to the reversal. I can only do this with a gimmicked deck. (Is it possible ungimmicked with the right 'skills'?)
Am I missing some?
