I contacted loomis about this, and they told me that they don't spline rods that are rated for under 20#, from GL2 to GLX. The reason is that the twist will not really effect the action of the rod at the lower line weight, so it is not necessary in the eyes of GLoomis to spline those rods. IMO if you are spending that coin, they should spline them just for the heck of it. But who knows if this will effect the cost of the rod even more.
