I am guessing that people shoot large shafts to help with getting better scores. Being a wimp and not being able to pull mega pounds so that I can shoot an arrow with a spine of .150", it doesn't seem like I can use the large shaft arrows. Has anyone considered a rule change to allow the use of a scoring disc which would be put around a smaller arrow so that the small arrow could get the same score as a larger arrow? Also is there a maximum legal OD for an arrow?
