Black Velvet likely has you covered....Like all setups it depends on a LOT of factors. Without going into those
I would do my BEST to get the 2018's setup for those rigs. IMHO its about the best shaft going for 50-60# Bows.
If you are at the above weights/draw you should have little issues with the 2018's ...Small dia. -thick wall=win/win;)
Point weight ? I usually run between 145gr-175 gr & 29"=30" shafts for my 50#-55# Longbows. I buy the inserts 3Rivers and others sell with the threaded end. I use basic metal screw threads to "fine tune" broadhead weight with the broadheads of my choice so as to match what is called for....
Best with your quest my friend.
