I run speed bows with 90ft.lbs.+

I have a Hurricane H-28, Hurricane H-25 (same as the H-28, just 25x25" instead of 28" and a Steel Stop bag.

Yellow Jacket didn't stop my arrows. "Classic" Block's don't stop my arrows.

I have a Glen Del Buck and Full Rut Buck, both stop the arrows just fine, perfect penetration, broadheads come out the back, unscrew and pull out the shaft.
