..........but IBO advertising is still BS. Wish I knew how you were getting even close to IBO speed with an actual hunting arrow.
No it isn't, IBO is a standard...... 30 inch draw length, 70 pounds draw weight, 350 grain arrow.
Just like ATA (AMO).... 30 inch draw length, 60 pound draw weight, 540 grain arrow.
Someone with AA or OT2 run an 82nd airborne or APA Black Mamba X1with a 30" DL, 29" arrow, 125 grain broadhead, feather fletched,Beman ICS 300and tell us what the spine chart says.
