You could run the numbers through Stu Millers calculator. I did a quick look and came up with a 30 f/s difference in speed. See attached images.

Total head weight 500 grs. Total arrow weight around 800grs. FOC around 32-34%. I’m shooting an early 70’s Bear take down recurve at about 54#.
My question is not whether or not these arrows are superior in trajectory and penetration, but how long it takes them to reach their targets.
Out her in Western SD I chase white tails and speed goats. I am wondering if the lack of speed in reaching the target is going to be an issue on these spooky critters. I’m mostly concerned about this factor for upcoming antelope season. They are so wary and spooky and very quick to leave where they were standing/laying if they hear anything! The bow is real quiet. I have not chronographed this arrow setup yet to see what it doing. Looking for feedback.
