If you play on PO FRs you get a chance to see a few different styles and try some yourself. You're generally playing a lot of the same plyrs so you can build a read. On 45 player and less you can develop what you feel comfortable with but that should always have a few wrinkles. You want people to build a read on you so you can exploit the fact that they are wrong. It's always about developing and adding from experience to your game.
