128/129 vs 136/137 track. Which Length is better?

The track length discussion has been a battle since they came out. "This one turns better!" "This one goes through bumps better!" "Which one is better for ditch banging?" I put a 128 XCR and a 136 XCR head to head in multiple categories to see where they shine. this test is also accurate for 129 / 137 as they are the same length rails, only difference is because the 129/137 is a 2.86 pitch track and the 128/136 is a 2.52" pitch, the actual track it self is about 1" longer because of the distance between the lugs. Watch to see which one is for you!
