Oracle,
Don't jump off the bandwagon too quickly. Experienced bowlers (myself included) tend to think newbies understand much more than some of them do, and we take things for granted when we refer to "roll out" or "preffered spin axis" or any number of other terms we deal with when trying to decide on our next purchase.
We have several balls (usually) and are filling small niches and tend to forget some folks only (only?) have one or two balls and don't have experience on a myriad of lane conditions. It can very easily be mistaken for indifference on our part. We know what we are talking about and just figure you do also.
In reference to your post, cupping your wrist is the quickest and most efficient way of producing more revs on your ball. Hand position and timing (hitting) the ball can also be useful tools to create more revs.
You must also realize that some people will ALWAYS put more on the ball than others and that it is not always how much you get on the ball, but in how the ball utilizes the energy that you have given it upon release. I will try to explain it like this.
A slick ball, (ie.. plastic or pearl urethane) will, under normal conditions, burn less energy on it's path down the lane due to the lesser friction created by the ball and the lane surface. If you put 20 units of energy in one of these ball, and because of the low friction, it only uses up 15 units, it will still have 5 units of enrgy in the roll/hook of the ball. It will still be trying to hook and roll because it will still have stored energy in it.
A friction ball, (ie.. dull urethane, reactives, or particles) will, under normal conditions, burn more energy on it's path down the lane due to the increased friction created by the ball and the lane surface. If you put the same 20 units of energy in the ball, and because of increased friction, it burns it all up at 50 feet, it will "roll out" and be dead on arrival at the pins.
The only cure is to find a way to impart more enrgy at the release point, or find a ball/fix the ball so that it does not burn up all the energy created by your natural release.
I have been bowling since 1980. My first years average was a whopping 120 and this year it is 228 on sundays. It takes time to learn the little things, but it can be rewarding when done properly!
