For those of you that have Arthritis and are having problems using a jump cue, the arthritis in your shoulders is probably your problem. A Doctor friend of my wife’s visited with us last night. We got to talking about jump cues and that I couldn’t use them very well at all. After I showed the Doctor a video of someone jumping and he listened to the instructions, he said that is my problem. I don’t have anywhere enough ROM in my joints to use the jump cue right. What really pissed me off was that after he watched the video he went out to the table and was jumping balls better than me in less than a half hour. He said he played pool maybe 5 times in his life.
