I'm about to build some Black Eagle X-Impact 400 spine arrows that have a .165 inside diameter. I wanna pick up some lighted nocks and narrowed it down to these two brands. I know Firenock is the best when it comes to nocks. I just don't wanna spend that much money at this time. I have shot the nockturnal lighted nocks in the past but wanted to hear some opinions about both of these. Which nock do you think is better and why ? BTW i was thinking about going with red to match my black and red SR6 i just built. Thanks
