Lane transition is a VERY hard thing to feel, and to adjust to. As we all know, and have struggled with, you really only have maybe of two or three frames to find it or else your game is shot. The house I bowl in, we also deal with that same problem. Most times the cause is the oil being pushed around by the other bowlers on the lanes with you. It creates what's known as "A Dead Zone". The oil is still out there, but because of several people using one track, the oil gets pushed out (right & left ) and you end up with a very dry center area. The "Trick" is to be able to follow the oil where you'll have a better shot. There's a great article in Bowling this Month magazine in the Dec 2009 issue dealing with this exact problem.
