Solid pull bar

[shaw33]

Running a usmts/usra style modified 4 bar/4 bar with a bushing style pull bar. I've heard recently some guys running a solid pull bar mainly in the slick. Anyone have any luck with this or bad luck?

Its the other way around. Run the solid bar when the track has a lot of bite and switch to the sprung / bushing bar when it looses traction.
