About a year ago I switched from a Bald Eagle windage top with a 3" Protektor leather front bag to a Shadetree front rest with a fairly thin bag with Cordura surfaces. The sides on this new bag are shorter than the Protektor I'm used to and I can't get as much side grip as I like, even using shims.
I love the rest, but the new front bag isn't giving me as secure a hold as I like. I contacted Butch and he said their rests don't come with bags, so the seller obviously added this bag. The rifle I'll be shooting most in this rig is a Savage Benchrest 6BR factory gun.
I'm considering trying out the bags shown below, one an owl ear and the other square cut. The ears on the square-cut model are 1/8 inch taller. Can someone tell me when and why you would pick one of these over the other? Which should give me more side tension and a firmer hold than I'm able to get now?

Thanks in advance, and if I've left out any critical info, I'm happy to add.
