The 3x3 twill RainSong uses is stronger for the same weight compared to the 1x1 they have to use on the neck. They use the tighter weave on the neck to prevent "visual flaws" around tight curves (it is even difficult to get the 3x3 perfect on the flat back as noted above -- I suppose the 2x2 for the Standard and Hybrid tops is a middle point). Given they've already designated the neck a CH with the inlays, it's too late to put clear on the "good ones" for more expensive models. But there might be a different build-up on the opaque necks which is not as clean cosmetically but less expensive in some way.
