never broke any tips on any of mine shooting fast flight string I normally shoot Flemish strings but have some fast flight on older bows an never had an issue.
That is definitely a longbow as far as string length you need to subtract 4" for Flemish or Dacron string and 3" for strings made of fast flight material.
good luck
I really enjoy it I have done the 3d circuit for years shooting a compound but the traditional shooting really keeps me interested and its a lot easier on my rotator cuff!
