George Headley (20s)
Everton Weekes (40s)
Clive Lloyd (60s)

Manny Martindale (30s)
Lance Gibbs (50s)
Joel Garner (70s)
Malcolm Marshall (80s)
Courtney Walsh (80s)
Curtley Ambrose (90s)
Sunil Narine (10s)
Looks alright I guess, although I can't help but think you'd get infinitely better results with Headley if you were to select him from the 30s when he was an unstoppable demigod-like batsman averaging close to 70 at Test level rather than the 20s when he was still uncapped but averaging 70+ at domestic FC level (which frankly wasn't particularly strong in the WI back then).
