1. I tighten the tips until they are completly tight, no room left to tighten.
2. Once they are completly tightened, they fly great for me , I have taken 3 deer using Muzzy 100 grain 4 blade broadheads shooting 57lbs this season so far.
Make sure you use a little elbow grease and get them tightened all the way. I dont know what else to tell you? Once I get them tightened all the way, I never have any part still lose.
