Someone who studied bows and tuning for years shared that with a Center cut or past-center cut riser, the arrow isn't sure which way to paradox coming off the finger released string.
Center cut or past requires a stiffer arrow because the shaft is getting the force directly into the kiester, and doesn't need to be lower spine to wrap around the riser due to paradox.
I like center cut now so I can tune the bow to the arrow I want, instead of making arrow makers rich chasing different spines to find one that is suited for my release, draw length and bow weight.
By shimming out the side plate, I can tune the BOW to the arrow more easily.
Just another view of a great campfire debate.
