Matters on what size tire you will ultimately run. I am going no larger than 37", so the 3/4 set up is, IMO, perfect for me, and I don't have to pay $1500 for a D60. If you plan on running larger than 37" tires, wait for a 60. Oh yeah, I blew up three 10 bolt rears with tires of 31" and 35", but I do have a very rare "Torquemonster" 305.
