Yep...I love how the packages typically say won't effect flight or something along those lines....adding weight to arrows is going to change its flight...whether the shooter notices or not is the question....
Forget what ones I had....they changed my flight....I didn't wanna spend the money to do all my arrows...at the time I do t think anyone was selling cheaper practice ones...so I gave em up....
Tried making my own which didn't effect flight that I could detect....hit a deer and it went out instantly. So scraped that idea too lol...
Great idea...but the cost outweighs the benefits for me...but I can track my arrows very well as of right now...
Adding weight ton the back will reduce FOC which isn't good...
