I recommend the Heavy in front, and medium in the rear. Its your rear springs that give you most of your "ride quality". And with that setup, you can add a front bumper, winch, etc and not have to worry about front end sag. Iv seen some of the med-light set ups sag quite a bit under a full load or a small trailer.I've been waiting for a thread like this for ever!!!
I'm definitely going with 31x10.5x15 tires.
Now my only question is which OME to get. Light/Medium or Medium/Heavy.
I used my 60 as a DD & very light off road (camping and such).
