String strand count will vary depending on the thickness of the strand which varies between the different materials. Your first decision should be type of material - Low stretch (Fast Flight) or Non-Fast Flight (Dacron, B-50). Your Bob Lee Hunter should be Fast Flight compatible (may want to call them to be sure) so you probably want a good low stretch modern material. All you should have to tell your bow string maker is your bow type (longbow or recurve), bow AMO length, Bow poundage at your draw, your arrow nock that you use and what colors you want. Depending on what low stretch material they recommend, the strand count will vary. For example, I like 450+. It is a pretty thick strand so I will only have 8 strands of that. But if I want to try BCY X, I would probably go with 18 strands because it is a much thinner strand. Also, your string builder will probably add more strands to the loops so they are "padded" and fill the string nock grooves of your bow more. This is thought to help so that the string is not so harsh on the bow (especially for low stretch strings)
By the way, I shoot Easton Axis trads as well and 8 strands of 450+ padded to 12 in the loops served with .024 Halo gives me perfect nock fit on the Easton X nocks.
Good luck to you!
