Rocksurfer did you just contradict yourself?
Let me quote
What needs to be done is equal comparisons, pit two equally set up rigs and see how far they can go before they can no longer move without help. That will show who has the best rig
A lot of how well a rig will do has to do with the driver, and his/her knowledge of the trails and the vehicle
My opinion... doesn't matter how equal the two vehicles are, it's all going to depend upon the driver.
