I always use stick for layins, it is actually the opposite of what you just said IMO - 'x' i use for spot up shooting, while stick for every move around the basket. Moving it different ways gives you obvious lanes to the basket x just couldn't - like if you're on the right side of the court doiing a fast break and a defender is waiting, there's nothing better than waiting for them to go into charge position, then moving the shotstick to the left and the (opposite) side of the rim to easily run around them for a dunk or easy layup. You can often do many moves people don't even know exist by simply using shotstick.
