I usually use REALLY long poi and wrap them around my middle and index finger, then use a key grip.
You can hold the poi in any way you find comfortable, don't be afraid to play around with different ways to hold them, you might find that the best way to hold them for you will change with your development.
If you want something to think about while finding a comfortable grip, its good to have a grip where you can feel the momentum of the poi and the tension of the cord.
In my grip, I can feel that on my thumb, Jameth can likely feel it between his index and middle fingers.
Have a great time, welcome to hop and don't be afraid to ask questions!
