I gave up on Executioners,, many think the factory arrows shoot good, but it is an Excalibur so any anything shoots good, if you want the bst O have proven the Zombies and the Spynal tapps will easily shoot better than the Executioners!!
Now if you want to argue a 350 grain light FOC arrow I may be wrong, but by the time you add enough weight up front to get 400 to 420 grains it will be capable of better accuracy using these two stiffer arrows!!! After much testing I never could get the Executioners to do quite as well as Zombies and Tapps, they may shoot good enough for some, but I want as good as possible, so if I want to ruin arrows if I shoot the same place twice, and 40 yards accuracy is important to me, these arrows may be more than necessary to you, they are to some. But with three ruined and one needing refletched at 40 yards they are accurate not wind sensitive, and quite accurate. 16.5" 410 grains, with Firenock D2 lighted nocks and blazer vanes, RH offset.
I like the DM string stops, Single Stage Target Trigger,, the factory trigger may be ok to you, but the Trigger Tech Single Stage is way way better, lighter pull, crisper break, and absolutely no travel, again, what are you willing to settle for?
Nice bow, it's up to you how much nicer,,, and how much accuracy potential you want to settle it!
