forcing
riffle force is great and my friend uses it religiously! i think its ok, but as said before the classic is the best. the only problem with these is whenyou get a heckler that stops you right at the begining or very end, so my personal favorite it the overhand shuffle force i learned on. . .ninja, 2 i think. its very natural and once you get the timing down its almost inpercivable, practialy angle proof and you can just glimpse the top card and go right into it. also it doesnt matter when they stop you it can be after two seconds or two minuetes only thing is you can only maintain a small setup at the top, but over all its my favorite.
