Just how much better is the G25's FF than the DFGT's FF? I have the latter and was thinking of trading it in to get the former. Though I consider myself, now, a more casual gamer in general than when I was younger, I'm pretty serious about total control in GT5 (I have been thinking of building my own Cockpit, but don't really know where to start.) Anyone have experienced with both and think that it is worth to it switch?
