Strong back end is something that is often misunderstood. A ball with a strong backend transitions really fast in the backends. These are gonna be asymmetricals and you can get the skid from the layout and surface. The IQ tour pearl is very continuous in the backends. It has a lot of hook in the backends because of this so a lot of people would call it strong backend when that isn't really the case. It's hard to determine which backend someone is really looking for between strong or continuous cause they are complete opposite yet are commonly confused with each other because of terminology. The number one thing that drives me crazy in the pro shop business is how terminology differs from one person to another.
I'm not so sure I understand the difference.
To my mind, strong backending balls should be continuous. A strong backend should not preclude continuousness. I will admit that some very strong polished pearls (even solids) can be so strong in some people's hands and on some oil patterns, that they roll out when they hit the dry. If a ball rolls out before it gets to the pocket, it is rarely continuous in my eyes. In that case, I think it's wrong to be using too strong a ball.
I am inclined to believe that no matter how strong the backend on a drilled, thrown ball is, if it's not also continuous, you shouldn't be using it.
BUT I could be missing some other concept here. If you think so, please describe it. We may be using different terms to imply the same or a similar idea. Thanx.
