Elk,

Not trying to tell you what to do but,imo, the PSE Gorilla from the custom shop and Bowman Accu-Riser are both superior bows to the Mathews Safari for shooting ultra heavy arrows from 80 to 100lb limbs.
The Gorilla weighs 5 1/2lbs and is extremely rugged but not in the same class as the Bowman.
Stewart makes a standard Accu-Riser II that goes 5lbs and an extra heavy version that goes 6 1/2lbs.
I have both versions and nicknamed my heavy version "Hercules" because it it Battleship strong.
It's the strongest built compound of all time.
The Gorilla goes for around $1,000.00 and so does the Bowman.
The Bowman is the far superior bow and much the better buy, jmo.
Here is a pic of Hercules.
