How often do you use the riffle force in your professional magic?

What adjustments do you make when you encounter a spectator who insists on choosing a card either near the top or near the bottom of the deck?

When they insist on going well past the middle, I sometimes pretend I lost my grip, uncut the cards, and do a slip force.

When they say STOP almost immediately I pretend I didn't hear them and let my thumb go closer to the middle, and then same thing, I can say oh I'm sorry did you want to stop closer to the top? And then uncut the cards and do a slip force.

I like the riffle force better than the slip force because I can do the riffle force with one hand and I don't risk the scraping sound when I let the top card fall.

Other thoughts welcomed and appreciated.

I use the riffle force all the time. It's all about taking control. I work in bars, so just be confident. If someone wants to be difficult, go to someone else.

I too use riffle force all the time. It's all about presentation, not a challenge and some "outs" know-how.
You can start slowly riffling down the edge and then ask the person to stay stop. If they wait too long,
you can use the comedic line, "Before I get to the end", and start over. If you know they are going to pick
the top card start over, put it there and let them take it. If they and grab somewhere in the middle, take it
from them and ask if they are sure, then perform a top change.

That's why it's so important to learn audience management and have an arsenal of "OUTS" know-how as well as card
handling skills.. (as mentioned) Don't make it about a challenge, rather about entertaining. Your personality and people skills
play a pivotal role as well.

If you are in a close-up setting without a mandatory sequence or certain order you do your effects in:

If you miss the force, just let them pick the card they want and do another effect by controlling the card.
The more you do your forcing method, whether riffle force or classic force the better you get in recognizing patterns in your chosen participants.
This allows you to be one step ahead and either select your spectators more carefully or guess on advance that they will go for the top card and prepare your force accordingly.

I also like the spread cull force as the participant can touch an card they like.

Alternatively, you can drop the selected card "by accident" and oh look at that you saw it. Therefore, it makes perfect sense that the spectator picks another card by riffle force number two.

The Slip Force has a bad reputation because it is often performed badly. This free manuscript explains The Deceptive Slip Force: (https://buy.bobmillermagic.biz/magic-1/65-deceptive-slip-force) I use it all the time when I perform PreDate - The NoMem Card to Calendar Prediction.

There's a subtlety in Card College that solves the issue.
