I like option #3...the .66 would be nice with my 4:10's and small polyglas tires on the street but it would be nice to see a 2:95-3:05 1'st gear for a more controlled launch with slicks. That would be the best of both worlds.
I really do like the close ratio's of my 23 spline and if that can remain with just a little more 1'st gear grunt it would be all I could ask for.
