If you go for the .64 fifth gear, you're going to hate the 1000 rpm drop when you go from fourth to fifth. I switched from the .64 to the .82 as I was tired of having a useless fifth speed. Granted I could cruise at 75 mph with the engine barely running, but when I wanted some spirited passing, I had to drop to fourth. Now I turn 2600 rpm at 70 mph and my engine is right in its happy zone if I want to accelerate or pass.

Leave it as it is.
