    * Center serving size depends on the number of strands of bowstring
1) Halo Serving: recommended on any string material as a center serving where increased durability is required. It is often the preferred choice of finger shooters. It is extremely tough, but a little more difficult to hold in place. It can also be used as an end serving on recurves, again where high durability is required.

2) The recommendations are basic guidelines. The main factors being considered are:

Nock fit, Arrow speed, String durability, and Safety

3) Use any good synthetic wax on BCY"s bowstring materials (silicone blend recommended).
BCY manufactures and supplies products in accordance with these specifications. If used correctly, the material will serve the purpose for which it was intended - a bowstring or as a serving material. All products we manufacture are extensively tested. We offer a full range of material for the archery market. There are many variables which can significantly effect performance of the bowstring material. Some examples include: Number of strands and/or of twists, type of serving material, tightness of serving material, width of cam grooves on bow, amount of lubrication, type of release, condition of cam wheel, yoke system on cables, degree of string maintenance. As BCY cannot control these variables, BCY cannot accept responsibility for problems arising from strings, cables or servings.
