RE: this "spine" predicament is getting me frazzled..
The 250's at 30" are over spined....
150's at 30" may work. You would be better off going with a 2018 at 30" or a 35/55 at 30". Carbon arrow charts are pretty much worthless for trad bows. They are spined for compounds off a rest with a release aid that causes paradox to be vertical. Put it this way, A customer of mine shoots a recurve that's60#'s athis 28" draw. Heritage 150's cut to 29" bop with a 125 grain head bare shafts perfectly for him.
And yes, your bow/arrow weight set up will kill a deer.
