I am looking at two rifle rests and would like some advice on which to buy. They are the Shooters Ridge Tri-Stance rifle rest with leather bag and the Cabella's Granite Bench Rest (over 14 lbs.). The bag on the Cabella's rest appears to be cloth or vinyl, they don't say in the catalogue. I would like to know the approximate weight of the Shooters Ridge model. Any information, opinions, or advice about these rests will be appreciated.
