I'm torn between these two. I've always used fmj but want to switch it up a bit. Feel like the fmj don't spin true after quite a bit of shooting. I'm not sure if I want to run a outsert. Im not familiar with them at all and my shop really doesn't either. Black eagle arrows are unheard of here. I like a heavy arrow so the deep impacts are what I'm drawn towards. Reading seems to be about 50/50 good and bad. Lots of nock problems and not spinning good with outserts. The Spartans seem to have only good reviews. Are they comparable in size with fmj? I just ordered my new bow. Hoyt carbon defiant 34. 80 pounds. Any info would be great. I've been shooting bows for 15 years now but never have gave much thought on arrows. Just always let the shop do whatever they want with them. So I'd like to make sure my foc is on and learn more about that. I also will be shooting either slick trick viper tricks or rage. Not sure yet. Thanks for any help guys.
