Mine's C&F Design. I like the fact that it can be weighted as to me it helps a lot when tying, I would do it even heavier. The best bobbin i've used but it's quite expensive. Best bang for buck would be Tiemco Standard Ceramic bobbin in my opinion but there are many good ones like Griffin etc..nice tie timo, where did you get your bobbin? looks nice mine keeps cutting my thread starting to piss me off
