Great post but I don't follow, HiRide.
You've told us many reasons why SMG is better (and runs faster) on track. However, you don't believe an SMG driver can hit a drift as fast - why not? You say it is considered 'one more fail point' (on that basis leave out the engine!).
However, SMG has a very good reliability record on road and track, is only marginally (15 lbs) heavier and protects other components (eg. engine from over-revving, and the clutch, maybe brakes too).
You obviously know SMG benefits, though I suspect it takes ownership to really appreciate (left foot braking is not essential). Yet you wouldn't trade that funny old 6 speed. Don't get it!
