While the elevated height certainly could, in some locations offer a better vantage point and possibly more shot opportunities. Before stressing yourself out and fussing with all that weight... I'd highly recommend, at least trying several times, instead, sitting at the base of that tree in a Leafy Suit with Matching Face-mask with a coloration that looks appropriate for the area... in as comfortable of a sitting option as you can find... and work on your holding-still skills. And also maybe pile-up a bit of deadfall from nearby to create somewhat of a natural gRound-blind. Only maybe even to like knee height or so thereabouts.
You will be amazed at how many things just don't know you're there, or even come up right next to you, if the wind is right! I've been very thankful and thoroughly jazzed for all the neat encounters I've had in just the 5 short years I've been at this, after I started wearing the leafy suit!
Besides deer, of course, one of the coolest ones... was having a little Cottontail... appear out from behind the scrub oak my sit was backed up against... and inching himself slowly, a bit at a time, getting right up beside me!!... even stood up on his hind legs and was trying to sniff for me in the air!... oh my goodness....so close! Like maybe just a bit out of range for me to kick it with an extended leg! Then the thrill of having to wait motionless... as he then receded back where he'd come from, which was directly behind me on the back side of that scrub oak. Then when he was out of view and I finally moved... thinking he was gone....he spooked... ran across thru the scrub oak.. then off the other way to my left... then made the fatal mistake of pausing to look back when he'd gotten to like maybe 15yds away from, and about to go into a bunny trail that lead into the taller grass. "POP!" Yayyy!! Then later that same evening... he's laying by my feet...I'm on my sit, surveying several places about my FOV in front of me... .17 HMR on the shooting sticks.. then I decide to turn and place my head 90 degree over my shoulder to the right and rest it on the shoulder of the arm that was holding the rifle in the shooting sticks in front of me... intending to scan these other 2 or 3 spots they come out sometimes... and in my mind I'm like "Oh HELLO!" Soo cool! A mature doe... feeding at maybe 30yds to my right! Watched her feed and feed as she kept getting further and further towards being behind me... until she finally caught on the wind current the smell of that Rabbits blood at my feet! HaHA!! Woohoo! She stotted off back towards the chapparral she'd emerged from nice and quick, throwing back one last bewildered look, still not knowing where it came from, just before she dove fully back into it!
