I had to chrony some bows awhile back for a customer.And testing the bows we also tested several strings.Larry Hatfield at Howatt had mentioned to me once to give different strings a try....We were haveing a little fun and testing about 12 different Kodiaks....I made a 60" 10 strand string,which fits most all my Kodiaks..But anyhow the 10 strand really made a lot of difference in the speed.I used the 10 strand on a 1962 Bear Kodiak 50#,I also used a fiberglass arrow (micro flight #7)with a 65 grain tip....It was 182 ft per.with a 16 strand and 190 ft per.with the 10 strand....But the light arrow and thin string (no string silincers)made the bow pretty load,and somewhat squirrly.I did add 4 strands to the loops for extra padding.Keep me posted,bowdoc
