Last, unless you plan to do some track days where you'll be exceeding 90 MPH, the 0.81 should be sufficient. Even if you do plan to do track days you may want to go with the 0.81. If you shift from 4th to 5th at 6000 RPM with a 0.68 gear, your next RPM at that speed will be about 4,000 RPM. That may be so low in your horsepower curve that you can't accelerate much faster. A 0.81 gear will put your RPM after the shift at about 4700 RPM in a stronger part of the horsepower curve.

Makes sense
That was my original choice but after talking to MDL he was suggesting the .68 if no track days or straights and a .81 if I'm doing a lot of track straights.
That's why I was second guessing my original choice of .81
