I am wanting to change arrows for 2024.  Trying to figure out my best route.  I am wanting to keep the arrow in the 450-475 range, issue I'm having is at my draw length and arrow length keeping an arrow that light drops my FOC.
I am not here to argue high FOC. I am only interested in keeping my set up ethical. Hunting western game, mostly deer but someday ill get an elk 

.  Shooting Sevr and Iron Will BHs.  Only shoot 63 lbs currently.  Goal is to be shooting 70 lbs by 2024.
Current arrow is an Easton 6.5.  454 gn at 9%. I can bump up to a 50 gn insert an be 487 at 10.5%.  Arrow is 30" carbon to carbon all arrows I'm looking at currently just using the same measurements for the sake of comparison.
2 arrows I am eyeballing are the Easton Sonic  and RIP TKO.  Both will allow me to run 50-60 grain inserts for a total arrow weight 470-480 and 10-12%.  Where im trying to stay lighter weight would it be worthwhile to ditch the lighted knock? I could also try and use different vanes to shave a few grains off the tail but I was wanting to just run AAE Max Stealth.
Just looking for guidance for those with more experience.  I don't want to drop the time and money on new arrows unless it makes sense.
