Certainly don't mean to question anyones methods , to each his own , .....I've found a straight stick ( mono pod ? ) works best for me. With most store bought rests they allow you to rest on top or in the "v" or some variation of that. Seems like Mr. or Mrs. deer always manages to show up in a dip, ravine or hillside or whathave you, making the height of the sticks unusable . By using just a straight stick you can adjust the height simply by sliding the left hand up or down the stick, then resting the weapon on my left wrist. (for right hand shooters ) Obviously I shoot a contender.....a revolver my burn ya unless you rest it from the grips. Most deer I've encountered won't give ya enough time to set up a bi or tripod. Course my method is not nearly as wobble free as afore mentioned devices, but a lot better than off hand. Now maybe if ya hunt from a blind with everything setup........only mho Sorry, after rereading the originally post, you did say about hunting from a ground blind....gonna leave this post anyway, it may help those of us that still-hunt.
