I use a C3 Winningbird, but accidentally bought incompatible C3 response pads to go with it. So if anyone has good CBC 19mm SLIM silicone response pads, I am willing to trade 3 C3 response pads for 2-3 CBC Slim 19mm response pads. It’s an excellent deal, especially if you use C3 yoyos. Contact telvinni97@gmail.com if you are interested.
