Lol... 6ft 3" and a little heavier now at 196lbs (winter coat).
I had a 360 until it RROD'ed. I have nothing against FM4... except that its track models are horrendously bad. I have only tried it with the MS wheel, but that is not worth anything. So truth be told I cannot judge its physics. However, I have always felt, in general, Forza is a bit "gamey" (in other words, I am rarely fooled into thinking what I am doing is real).
If I am not mistaken the world order of realism goes like this (console sims GT/FM) < (pc sims rFactor/LFS/Netkar) < (iRacing). That middle area is always a pissing contest, but they are all about the same.
While I am not a huge fan of the T500RS. I got mine for $381. Thats is pretty good when compared to a CSRE. At $500 or $600 the T500RS, value wise at least, is worse than the CSRE.
