I just love the runner. It gives you better traction on and off trail. If the willie is still in your mind then go with one with front end heavy put on some wiegh in the front.
Back to the question tg kit and all pro kit.
I'm running all pro 5 front and marlin betts 5 in rear works fine they flex pretty well on my 2nd gen 3.0.
My buddy is running tg 5in kit on his 3rd gen works all rite I don't like the flex. Maybe that their front spring is a bit shroter then all pro and marlin.
Here's a link you can see both the runners
