I have shot for 37 years and i really never did use a jump cue much. I have always relied on my kicking. But in the past month i have been trying to improve my jumping. It is taking a toll on my shoulder and ribs. I dont have any problems getting up over the ball but i cannot make a ball 3 inches from the pocket. I cannot get my stroke straight and never usually hit no where near center of the cueball. When i have a close ball i need to clear i have to use a dart stroke and the accuracy is really bad.
