What do find to be the best center serving material?I am using #62 and find that my nocs are loose.Can I double up?Ron

Center serving comes in different diameters like .018, .021, and .025" . you may have to either bump up to the next diameter size for your center serving, or get a new string with more strands in it to increase the bundle diameter.

I have known some people that want to get around this and they lay an extra strand or two of string while they serve over it to increase the diameter- I don' t like that method but I suppose it may work in a pinch.

Make sure if you double up you don' t get the serving too large. Your group will suffer if your knock doesn' t come off clean and fairly easy. My thought is to go to a nice larger size mono. Just my $.02.

I agree with 2hunt. Go the the next larger serving. It' s not best to get a string with more strands if your bow shoots OK. More strands will just slow the bow down.
