Rage hypodermics+p are hard to find around here. I have 5. But I like to have at least 8. Can't seem to find replacement blades either. Fixed heads are not as hard to find. So I am thinking of buying a pack. For back up. What you guys recomend? shooting 61# at 26.6" draw . arrow at 390 gr. thinking standard slick tricks..they have done well for me in the past with different set ups.
