Harmison steamrolled the Windies twice and the Kiwis once, and may roll over the Indians when the English come on tour. Akhtar is one of very few pacers who can upset the Australian batsmen, and he's a genuine matchwinner for the Pakistanis (none of the Indian pacers are matchwinners) in all conditions. Bond was good in Goldfinger, which Australian, West Indian and especially Indian teams would do well to remember and would be the #1 pace bowler but for injuries- name one Indian pacer who doesn't get injured.
Kaspa's no great shakes- his average is in the 30's. Gillespie is capable of bowling at serious pace, but chooses not to overdo it. Moreover, if the recent VB series is an indication, Lee is a contender for best ODI bowler. Even in FC matches, he can take a bucketful of wickets- he was dropped from the Ashes squad and told to take wickets for NSW- he took 21 in 2 matches and returned to rip through the English batting lineup. West Indies played some genuinely quick pace bowlers, but they got injured a little too quickly, at ther wrong time. South Africa's Andre Nel has been in very good form.
Look at the top Test and ODI teams- they have at least one genuine fast bowler in their ranks.
