QUESTION: other thing i want to ask you, what about using platies to cycle my fish tank.

Answer
Jeeva,
I really wouldn't use any fish to cycle a tank.
It hurts them when the ammonia goes up.
Search the Internet for "Fishless Cycling".
There are a ton of articles out there to help cycle your tank without fish, but Platy's are not the way to go.
