First of all, Where in the heck did you order a G27 from because I'm looking for one myself! lol... Everyone seems to be out of stock unless you paid a premium dollar for it.
I was also having a hard time trying to decide which wheel to go with. The Thrustmaster is very tempting but I can't really get over those hard mounted shifter paddles. I just know it would annoy me, especially while racing Cart or F1.
Each wheel has it's pro's and con's I suppose. Tough decision to make no doubt! I personally like the idea of slapping on a 2lb 330mm MOMO for my rig.
Since the G27 is out of stock right now I have been burning a hole in my pocket impatiently waiting. I have the CS Pedals and a SST shifter on there way. That will work nicely on my PC setup and with the G27 package I will have pedals and a shifter that will work with GT5 as well.
I hope the G27 comes around quick before I buy a Butt kicker or something! lol...
If you recieve the G27 soon please do share how you like it! Thanks
