The lower skirts are partly a design element and I do think they add a little depth to the look of the table. But maybe they also serve the function of hiding the bottom of the drop pockets. I've seen pics of tables where these were scrapped and you could see the bottom of the pockets sticking out below. Now I'm not sure if the original pockets would stick out. My understanding is that originally the early GCs had shorter pockets that didn't hold as many balls. Maybe the pictures I've seen that I referred to had newer pockets installed on an older GC.
Monte, the pockets are original, right? How many balls do they accept? Can you tell if they would show if the lower skirts weren't there? BTW, I predict you will come to prefer the drop pockets, especially if you're having back problems.
Both the GC1's & 2's came with the plactic skirt extentions because the side skirts were not long enough to hide the drop pockets or the ball return. The GC3's were changed to have longer skirts...to hide the drop pockets, therefore the plastic skirting was dropped.
