at least you have a 8.75 so switching ratios is "easy"...
i've always considered 3.23 to be the compromise, relatively easy on cruising RPM and easily adjusted up or down with reasonable tire sizes that are widely available and don't look like truck tires; but with enough punch to get you up and out of the hole.
a 2.9x or there abouts would make a great road gear if you have the torque to pull it both on the highway and around town.
anything sub 3.55 would benefit from a low gear set, imho. and while having some stall is always good, that lower gear might allow you to get away with stock stall.
