Found this from the Genii forum written by Paul Cummins:

1.As has been stated by a few, the performer should be looking at the left end of the spread cards in search of the target card or cards to cull. This is so that you gain a second or a half-second on your decision to cull before the card reaches the middle of the spread to be culled and helps to avoid a change in rhythm when the cull actually happens.

2.Very importantly, *both* hands must be moving towards and away from one another during the entire spreading process. This movement will also help to disguise the actual moment when a cull is executed. Helpfully, it also helps you to establish the rhythm mentioned above.

3. Always hold the cards very flat and very gently (almost *loosely*). When first learning the cull, and many sleights, the tendency is to grip the cards with more tension than is necessary or desireable.

4. It is helpful to slightly outjog a group of about 5 or 8 cards early in the spreading process (close to the face of the deck) as this *slightly* outjogged group will help to provide cover for culled cards as they are delivered below the right-hand group.
When executing the actual cull it is best to deliver the culled card straight across to the right. However, the performer should tend toward culling the card a bit closer to the inside short edge of the right-hand-held cards than to the outside short edge. Even if you can get a quick glimpse of the card at the inner edge of the spread as it is culled, your audience will not - and certainly they would see the card at the outside short edge if you
were to tend that way.

5. It is only necessary to place your left thumb against the card above the target card in the spread on the *first* card culled. This, of course, provides friction that prevents the right-hand cards from moving to the right as one's right fingers cull the first card. After the first card is culled then you may use it to clamp the right-hand cards (using your right fingers to hold the culled card against them) during the subsequent culls. In fact, the
right fingers need not pull the cards culled after the first one to the right - the left fingers may literally deal (or, deliver) the subsequently culled cards below the right-hand spread. This is another function of moving both hands toward and away from one another and of establishing that rhythm.

6. After the first card is culled it is used to clamp the right-hand spread until the newly culled card is delivered below and against the previously culled card. This happens as the hands come together during their to and fro movement; the left-hand spread is pushed slightly further than usual until the right fingers can gently grip (*not* pull) this newly culled card. As the hands separate the culled cards are allowed to rest on the right fingers and the next time the hands come together the left-hand cards may be fed between the right-hand spread and the cards lying on the right fingers until another card is spotted at the left side of the spread for culling.

7. After the first card is culled, subsequent cards are culled beneath one another. I've found that many folks who ask me about the cull are able to cull one card but have great difficulty culling more than one card because they are trying to cull subsequent cards *above* the previously culled card...

8. When two cards you wish to cull are together in the spread cull them as one card, do not cull them separately! This requires a slightly larger in/out swing with the hands, but that swing is far more welcome than breaking the rhythm you've established by culling the two cards individually.

9. It is helpful to keep your left hand slighty forward of our right hand and spread the cards at a slight diagonal from your left hand to your right.

10. If the card you wish to cull is at the face or below the face card, cut the deck and respread; or, spread about 7 cards into your right hand and then push them into the deck as you square in order to stop what you're doing to make a point with patter. Then begin to respread and proceed with the cull.

11. If the card is third, fourth, or fifth from the face, slide the entire small spread of right-hand cards over the target card until it is well below the face card of the little spread. Now pull your left hand to the left (beginning the in/out hands movement and starting to establish that rhythm) until the right long side of the card that was below the target card snaps lightly off the left long side of the target card and continue spreading.
