With each table and cloth being different, you need to make slight adjustments. Most of the time when playing with a "mud" QB or a "magnetic" QB you are unable to draw it so you have to adjust your shots, which means you have to adjust your approach angle, which means you have to adjust your pattern play a little. You will find it much more rewarding to use follow with a "mud or magnetic" QB. Some cloth plays slow, some plays fast. Look down the rail and look to see if theres a STRAIGHT line worn in the cloth, that will give you a pretty good reading that the table rolls straight along the rails. Look to see if theres a QB pattern worn in the cloth when breaking, that will give you a hint also. Check out the angle of the pockets, this will help you determine if you have to hit the back of the pocket or can use the rail just before the pocket.
Best of Luck!!
