RE: field points to broadheads
CBM is right on. I can add little or nothing to his advice. Man, I do hope those things were aluminum arrows though. And your shop guy was not out of line just in case you need to know. It is not their job to take care of all the little details such as spin-testing arrows. That's akin to taking your car back to the dealer every time you want to get the air in your tires checked. You learn to do this stuff yourself, which you are doing, and you'll have a much better understanding of what makes all this stuff work and how to correct flaws. Then you'll be like a lot of us on here. Not asking a lot of questions, but passing on the info to another based on what you've learned. And I can say, there's always something to learn in this sport. Good luck.
