Based on what I've seen with people who throw both balls, the Flashpoint is more of a skid/snap reaction ball and the Flash Force is more of the arc ball. I think that would be a good one/two combination, especially if you bowl on a lot of medium, medium/heavy or medium/light oil conditions. Up in my neck of the woods a lot of people have been shooting a ton of honor scores with the Flash Point as their number 1 ball, and I've seen others throw some high 700 series with the Flash Force.
