Andy, I am on my 2nd 80 series truck, having owned them off and on for almost 11 years now, and have had 2 different OME setups on my rigs. My first truck was on J springs, and my Lexus has heavy front/heavy rear with 1" front spacer. looks proportional with the 35" tires, and with the nitro charger "L" shocks it rides pretty good. I have front and rear bumpers, and it still rides a bit stiff, so a medium setup may work great for you. That said, if I were to do it over again, I would be interested to try another manufacturer like Dobinsons or the Tough Dog that Trail Tailor distributes. If I had the $$ I would look into the Slinky setup, but that is some high dollar stuff right there. You can buy an 80 for the price of that suspension!
Good luck, man!
