I would like to shoot in some IBO events this year for the first time. I shoot a Mathews Icon, 9" Sure Loc sight with a 4 power lense, a 24" Doinker stabilizer, and CLX selects with 1.78" Easton vanes. My question is this, with my setup, will I have to change anything to shoot IBO, and what class would I shoot in? Any advise would be appreciated.
