Wrong forum. This is elk hunting.there's a reason you will never see a whisker biscuit being used by a professional archer.
Shooting from a line in Vegas with fat arrows is not climbing over rocks and stalking through waist high sage brush which is also why the pro's 30" stabilizer isn't a great idea.
Any rest will work but a WB is one less thing to go wrong when you have invested the time and effort to get a shot on that elk.
