Trying to make sense of the different bowstring materials and how they relate to different styles of shooting can be very confusing. A trusted source of archery knowledge is two-time Olympic medal winner Jake Kaminski.
In this informative video Jake Kaminiski gives a concise breakdown of the string materials used with modern recurve bows.
Comparison
- BCY Spectra 652 = Brownell Fast Flight
- BCY B55 = Brownell B50
Please note that modern materials are not meant to be used on vintage bows of any bow without reinforced limbs. It is HIGHLY RECOMMENDED that Dacron strings such as B50 or B55 be used exclusively on these types of bows to prevent bow failure.
