The less travel you have the worse the ride will be. 3" coils simply remove 3" of travel from your suspension, whereas a 1" coil is only 1". Add spindles and you drop 2 more inches without affecting the ride whatsoever. so the best ride will be from the spindle, spring combo. I suggest the spindle drop since you might get a wild hair in the near future and want to bag your truck and you're gonna need them.
