Like I said, "look at the way you make strings", 24 strands, thats a rope, 14 would have been adequate but I would have gone with 16 just to be on the safe side.
24 strands of B-50? Rope? More like a naval ship hawser!
That's 2,700 lbs of breaking strength when all you really need is 4 times the draw weight. But then, some of you jokers in here pull some mighty heavy bows, too. I'm a wimp.
I've been getting away with 8 strands of B50 on bows up to 50 lbs of draw weight. Yeah, it's initially pretty stretchy, but they do shoot-in pretty quick. Mind, I do have to double serve the area where I nock my arrows in order to not cut thru my glove, 8 strands is pretty thin. When I make strings for others, I do bump it to 10 strands and sometimes 12 depending on what they want.
I've shot some FF on my bows and just didn't notice any difference. So, I have allowed myself to take the cheaper route.
A couple of people have said they go with B50 because it's "good enough". I guess I'm in that camp too. There comes a point I just don't wanna go down the path of chasing every spare FPS out of my arrows. If I was worried about this I'd chick the wood and buy a Matthews 4 Wheel Drive GPS Enabled compound running prorietary software based on Linux++ and 8K Terrabytes of memory.
It's a personal choice, and personally I find the FF outa my price range. When I get into making flight bows, I will certainly revisit this chain of logic, you betcha!
