desired tire size and type of wheeling are huge factors in this. if u wanna put shiney little 33s on it and bling it out to drive to work and back, then a 10-12 bolt will be fine, judging from your username that doesnt sound like the case. id definetly go up to a 14 bolt, theyre cheap, easy to install and it'll never break. and for the front, it still depends on a few factors, tire size and type of wheeling. rocks and anything above 35" will break D44s and 10 bolts. mud and decent power with heavier tires (36" and up) will break them as well.
