Pish posh! Like I said earlier, I've tested this 'theory.' I tried a 14 strand FF, and a 20 strand FF, and I found ZERO difference in cast, all else being equal. With the 20 strand string, I didn't step back and go "holy shit, my arrows are falling 20 yards short." And, the 20 strand string is a lot nicer on my fingers!! The difference in weight between a 14 strand and a 20 strand string is NEGLIGIBLE. I've weighed them on a sensitive grain scale, and it's such a small amount as to not make a difference IMHO.
