Converting Slow-Twitch to Fast-Twitch Muscle Fibers

Also is hand speed in correlation with fast twitch muscle fibers? people think that hand speed is natural and "you're born with it" but 'im just wondering if it's in correlation with fast twitch muscle fibers, and you can develop those type IIb (super fast) fibers, then wouldn't that dispell the myth?

Although some people may be born with quicker hands than others, that doesn't mean that you can't develop your handspeed so that it's quick as theirs. In other words, some people just have a 'headstart' if you will.
