Very interesting. I spoke with Tony at JTS earlier today and he suggested the 1/2 kit. He said that it gives a nice stance and appearance. He said that the 2/3 kit is a bit more aggressive in stance but it will, depending of road conditions, bottom out.
In that the need is for appearance and ride, I am thinking that the 1/2 is a better choice.
In spite of having the highest gas taxes in the world, the roads conditions here in The Land of Fruits n' Nut's boarder on the original Oregon Trail and I would not want to have it bottoming out.
I put JTSVP's 1/2" on my truck, didn't notice any difference in ride quality, and still running the stock shocks. I really wanted 2/3" but I read the bed can only handle about 400lbs before resting on the bumpstops.
