Ya, i just realised that jiggling motion is a bit too much, but the jinggle motion also help me to hold the break behing the deck. Actually I still thinking of cut out this sort of motion in my zarrow shuffle.
Yes, i do a little jinggle motion when i shuffle cards straight, it helped to square the deck neatly and i thought it consider as fake resistance in zarrow shuffle?
Thank for the advise man, i've try all the grip and found that i cannot do a great deal by using those grip that mean i can only use this kind of grip to execute the move...sorry for my broken English :)
My bottom deal video was taken in both right and left angle
any criticism just say :)
