The G25 has awesome paddles and I was always used to using paddles before I got the G25, now I use the shifter, mainly in sequential mode when racing online, I wont go back to paddles now, I love the sense of immersion that taking your hand off the wheel gives when shifting.. its not so hard to get used to, heck I dont even use a stick shift in my company car since its auto and I still prefer the shifter at the pc.
Give it a try Jarkko, its great really, and wont take you long to get used to it and be just as fast (god forbid)
