Plus you also get the 2.87 1st gear, that turns my 3.31 rear into the equivalent of a 3.77 when compared to a Muncie with it's 2.52 1st gear. It works for me. Your driving habits are different and if I used my car like that I'd most likely get the .68 too.
My 2.20 first gear with the 3.31 is obviously doable but the 2.87 should be much more pleasant. So you get a 550 rpm drop going to 5th?
