For me...
If were talking a mid 9 second car here.
Street with some Track: D&D 6-speed.
Track With some Street: Proshifted Tremec with overdrive left in.
Track Only: Tough choice, but either a Proshifted tremec sans O/D, or a Jericho.
I personally will not own or race an auto. I know how good they are, how consistent they are, and how much fun people claim they can be (I have driven fast versions of lots of trannys) but for me, I cannot see myself without having to stab the clutch and slam the next gear!
