I use B-50 on most strings that I build. Looking at all of the posts about skinny strings has got under my skin. I want to build one. My question is what strand would I need of 8125 for a 67@28" longbow. I will have the loops padded with B-50 to about 12 or 14 strands.
Might sound like a dumb question, but I don't want to goof up my baby...
I would probably go with 14 strands. My opinion if you draw 28
Dont forget that only lighter bows shooting light arrows really show alot of improvment from using a skinny string. So at that weight if you shooting a big heavy arrow your wasting you time to gain 2fps.
When BCY published breaking strengths, they gave 8125 a rating of 120# (static load, not shock).
Personally I'd go with 12 strands, with 18 in the loops. I pad my loops with dacron.
I wouldn't expect any big speed gains, but it might make a difference in noise. That's what I've heard the most about--rarely if ever a noticeable speed difference, but often it can make even a quiet bow quieter.
With 8125 you will have a more durable string that has a lot less stretch and creep than dacron also.

Thanks Chad for mentioning, "static, not shock strength".
I hope folks will pay attention to that statement.
