What is your set up? Bow make / Pounds your drawing / draw length / arrow length and spine / brand of broadhead . And yes 100 grain heads and points.
Diamond Edge SB-1
60 lbs draw (I think)
27 1/2" draw length
28" arrows 340 spine
Cheapo broad heads bought through Amazon. Aiskaer 125 grain
As others have said your a little stiff on your spine, my sons specs are same as yours and a 400 spine arrow tunned extremely well for him. As for the broadheads how do they spin when installed on your shafts? Do they wobble when spun ? A wobbly broad head will steer a arrow all over the place . I highly recommend purchasing a quality brand name broadhead, a good broadhead that spins true will go a long ways in helping the tuning process.
