Everyone be careful on a whole. I think i'll manage rain if it happens, light rain for sure ,but heavy rain, I don't know. Light rain feels like just a bit less grip than dry conditions, and heavy rain is incredibly slippery. And it's also pretty hard to see, too. Yuo should've seen me swerving around the straights when behind someone trying to find some sight. And since I don't use the racing line, or any aids for that matter, you need to see everything in front of you to set up properly.
By the way, the cars all do feel different online. I haven't driven many of them for long periods of time to know about them, but i've driven the HRT, Mercedes, and Ferrari the most so far of any others, and the HRT feels understeery, but very stable and under control. Mercedes is also very under control and stable, but it does handle well. Ferrari changes direction well, and isn't too hard to control, but it may bite back. Ferrari feels best, and i'm not jsut saying that because i'm a Ferrari lover, but I haven't even driven the McLaren, Red Bull, Lotus or Virgin yet, plus have only driven the Williams, Force India, Sauber, and Torro Rosso only in a few short races.
