A word of advice: use a B50 Dacron string only on this bow! Most Hi-Speeds I have seen have no tip overlay, and I saw one this weekend with a limb tip destroyed by a fast flite string without padded loops. The man lost a good bow by using the wrong string for that tip. I say this as an advocate of low-stretch, skinny strings, even on a lot of old bows. My bows have survived at least 6 or 8000 shots with such strings, but the loops are always padded and I would never use one on a tip like the Hi-Speed, or a Herters, for example.
