Use the following trick to get the most out of your created fast bowlers (from medium bowlers to fast bowlers). Redistribute the stats so that you max out as much as possible on his accuracy and speed, then distribute the remaining points evenly over air (swing) movement and bounce (for cutting the ball). By doing this, if you have a fast bowler you can beam up fast bowls of close to 90+ mph with accuracy. This is especially useful when you acquire the "Heat Seeker" and "Extra Tools" cheats.
