Quilt E, Quilt E, Quilt E. You're just going to make your head hurt. Don't over think it. Which felt best for you. Which method gave you the most natural movement, the smoothest track.
Whether you have a pre set spine really determines the method. And of course if you have a spine with dimension, you don't usually cross over.
There. Have I messed with you head enough for today?
