I have an 06 Allegiance and needed to run it using my speed and arrow weight. The bow is an over achiever. Post your speed and your arrow weight and I will customize the BPF for you and let you know. @ 28" and 60 pounds with a 27" arrow I had to goto ACC 3-49's which by the bows database BPF were pretty stiff. Once I calibrated TAP to the bows actual performance I was able to tune them perfect.DAVID S. said:Speed Mods ,30" Draw 60#'s Fallaway Rest 3 Two Inch Blazers. All The Charts Say .400 Spine But They Seem Weak. Any Suggestions Will Be Greatly Appreciated. Thanks David
The 400 is pretty weak, and the 340 shows as stiff but this how the 3-49 looked right out of the database for me too......pdq 5oh said:Depending on point weight, a .400 arrow would be ok. If you want to use points/broadheads heavier than 100 gr, you should go to a .340 spine. In arrows such as PSE or Carbon Express, a 300 would be best.
