Hi Barry, the "Align to surface" option was meant more to handle something vertical to the surface like a cone sticking upwards like this:







The rotation around the surface normal is currently arbitrary which doesn't really matter for the cone case but isn't good for your case.

I'll see if I can modify the behavior to make it pay more attention to the path tangent direction as well as the surface normal instead of only using path position and surface normal like it currently does.
