Noob Slider Question

[jsquigg]

I love playing Fifa, but I noticed that most people on OS play with full manual sliders and at WC or higher. I'm still playing on default Professional (admittedly I'm probably still a casual Fifa gamer) and being challenged.

Does anyone have a decent explanation for going full manual?

Also, does anyone have any links for getting better at the game if it involves more than repetition?

I've tried full manual in past Fifas and gotten my butt handed to me using orion's or community sliders. I want to start a career, but I want it to be as sim as possible too. Any advice would be appreciated.
