Rests come standard with .015 thickness fins. There are also 0.023 and 0.028 thickness fins available. Sometimes shooters feel they shoot better groups with a thicker set of fins. Other times, the thicker fins may be preferred by archers using heavier arrows (over 500 grains).
0.015″ thickness (arrows under 550 grains)
