This has been a great post as I encountered difficulty with the cull earlier this summer. Below is a post I submitted to Richard James' board http://www.cc-magic.co.uk
several weeks ago.

==================================== (posted 6/21/08)
Since it's a little after 3am here in Florida I think I need a 'sanity check' regarding my studies with the Spread Cull.
I began with with Giobbi's teaching of the technique in CCv1 (CCv2 on CD-ROM) I found myself making progress each day following his instructions (pull with RH fingers).
At first I was not satisfied with how I was holding the packet of cards in the RH once the object card has been culled. At times the culled card flashed and often embedded itself in the 'v' between my thumb and index finger while the packet of cards on top slid around the RH.
For some reason I just wasn't 'getting it' and I think buying and studying Iain Moran's The Cullfather helped.
Moran has a slightly different take on pushing / pulling than Giobbi and I'm still pursuing Giobbi's method but did pick up a subtle detail from Moran that works with both methods and has helped me.
Finally after looking at the 'view from below' video clip on the CCv2 CD-ROM, I realized I was holding the culled card/packet of cards too deep in the RH. I was literally jamming it into the 'v' between the thumb and index finger.
And I was clamping down on the cards like I was trying to break a walnut.
Once corrected with the cards now resting more on the fingers vs. deep into the V of the RH the move looked much better with no flashing of the culled card. Also I relaxed the grip so my fingertips weren't turning white anymore.
My current challenge is now culling multiple cards.
I started studying the spread cull since finding what I think is a very strong card effect in an '05 issue of Genii. The original presentation comes from Vernon with enhancements by Giobbi & Johnny Thompson.
The effect calls for culling two cards that match the top card of a face down deck. This is done under the cover of searching through a face up deck and taking out 4 of a kind that contrasts with the top & culled cards.
What I need to overcome is I have small hands. Now that's not an excuse but the reason I believe I'm having difficulty with culling the second card.
In order to keep the first culled card in place in the RH and the packet cards that's associated with it, I have very little finger length left on the RH to pull the second culled card. Since my RH pinky is at the bottom of the cards for support, I only have the middle three fingers to work with (index, middle & ring) as the thumb is not an option.
What I'm finding is as I wriggle my RH to try and get some finger length to pull the next culled card, the packet stays on the RH fingers but the first culled card ends up either moving back into the 'v', up jogging so now half an inch or more is flashing or it begins to buckle in the hand which also lends itself to flashing.
So has anyone else experienced anything like this before? Or does this simply sound like a typical issue that will eventually get resolved with more practice?
I haven't given up as the cull is necessary of a Giobbi routine described in a Genii issue from a few years ago (Roberto's version of Vernon's 'Matching the Cards').
Some of the additional tips given here are in my 'queue' to follow up this weekend which is my idea of how to spend a holiday.......with a pack of cards and some new material to study.
Thanks all for a very helpful post!
