The rollers control the main ratio and that tension controls the clutch springs. But how do each effect one another and acceleration and top speed. Can anyone explane in laymans terms how this all works?

It is a bit complicated, but there's a pretty good explanation here...

The belt and pulleys are always turning. The depth of the belt in the pulleys is governed by the weight of the rollers, and the tension of the torque spring. A lighter weight will not force the belt out of the variator at lower rpms, giving you a "lower" gearing. At a certain rpm governed by the clutch springs, you begin to move. You can adjust where the belt rides in the pulleys before you move with different weight rollers. You can adjust the rpm at which you move with clutch springs. You can adjust where the torque driver up-shifts with a different torque spring. Most of all this is based on the motor itself. Where it has power, and how hi it can rev. Just like cooking, its a mix of all the ingredients. If your cookies suck, you're slow :smokin:

Like the internal combustion engine itself, it's amazing that it works as well as it does, or that it even works at all, without flying into lots of little pieces.

If I no longer feel the "shift" would that be a torque spring that is too light or too heavy. In other words before I started having all my top end problems I would get on the throttle and litteraly feel the bang of the upshift where it starts to really dig in and acclerate. I tried the white and the red malossi springs and have a set of heavier rollers on the way. Does anyone know what strength torque spring is suggested for stage II? I know there is a yellow that is supposed to be somewhere inbetween the white and red.

you should never feel a shift. The "shift" is simply you hitting your powerband. I like to be in the powerband ALL the time! o_o

Am i understanding you right?
