But as you can see in the first image I posted, the witdh between "Nose-Middle of the bindung" and "Tail-Middle of the binding" arent the same to begin with. So, I would never have an equal "twin"…
Am I wrong?
As hktrdr has pointed out to me, the Crail is supposed to have a slight setback, just not as far as you have it set up currently. As the binding distances are already slightly set back, you can't have an equal twin, but you can definitely changed the distances to help centre your weight.
Anything else will have to come down to a change in riding technique. Do you find yourself learning backwards a lot?
