ekaj Man, I don't know. I don't play TM drivers (haven't in at least 6-7 years). But, I think this one feels and sounds better, to me at least, than the Sim 1 did. I have no clue if it is any better numbers-wise for anyone. Just my observations from hitting it a bit today and seeing some TM guys I play with often hitting it versus their old Sim.
