I looked on the Cabelas website and didn't see any nocks listed for the SST arrows, but if I remember correctly the nocks you are talking about were just like the Beman nocks. As for the size of my arrows, I think they are 230, but I will have to look when I get home tonight and confirm.
BenBow, what type/brand of nocks do you have? If I could just get some idea of what types will work, I will scour the internet and find some.
I seen some SST on ebay that seemed to indicate they are made by Easton, does anyone know if this is true? If so, what was the Easton branded arrow of the same type called? Maybe that would make it a little easier to find components.
