Getting ready to order some surewood shafts and would like to get in the ballpark on spine. I have a BW PSA 58" 47# AND 53# AT 28" draw length.

honestly, order out a spine test kit of surewoods.  that's truly the only way yer gonna know what will and won't work for you and yer bow.  either that or borrow as many opa's (other people's arrows) you can and shoot outta yer bow.  a spine test kit will be a nice tool for any and all yer present and future bows.

have fun!
