Hmmmm
I would bet that the answer is the Chinese made Cuetec going by individual brand. The skinny is they shoot OK, but the fiberglass gets "gunky" fast and then you gotta wear a glove because it does not slide well no matter how well you clean it. And they do in fact warp, the fiberglass only helps protect from warpage, but it does not completley elminate it. Pretty popular with the bangers due to the price.
