Based on Pearl Drums recommendation, I built a 14 strand D10 string, and padded the loops to 18. Maybe unnecessary, but as it's my first Osage self bow, and first time using FF on such, I erred on the side of caution. 14 strands of D10 served with .024 62xs just gives me good nock fit for 5/16" Bohning nocks on a tapered shaft.
At this point, I have approx. 300 shots with this string and after examining the nocks with magnifiers, I can honestly say....not a single issue, well except for the increased performance, decreased noise, vibration, and hand shock! Use with confidence as those with waaaaayyy more experience have said above.
