Controller for PS2 - GT4

[cooperluke]

Hi, I've recently bought my PS2+GT4 and I'm still starting the game.

I don't have the steering wheel (yet) so I have two options for controlling the car.
Or I use the "X" for throtle, the "square" for brake and so on... or I use the two "gameshocks", I think this is the name.. the two analogic joysticks to handle the car.

The problem is that I find much harder to control the car using the analog joysticks...

You, that have more experience, tell me what kind of control you use. I think the analogic has more control potential but is harder to learn. But, is it worth my time?? Or should I use the "normal" controls only??
